wifi: ath12k: fix stride mismatch in mac_phy_caps_parse()
Currently, in ath12k_wmi_mac_phy_caps_parse(), kzalloc() sizes the
mac_phy_caps buffer as tot_phy_id * len, where len is clamped to
min(firmware_len, sizeof(struct ath12k_wmi_mac_phy_caps_params)). The
subsequent memcpy() destination advances by sizeof(full struct) per slot
via C pointer arithmetic, not by the clamped len. When firmware sends
short TLVs, the second and later slots are written past the end of the
allocation.
The reader in ath12k_pull_mac_phy_cap_svc_ready_ext() also indexes the
buffer with full-struct pointer arithmetic, so the allocation must match
that stride.
Fix by using kzalloc_objs(), which derives the element size from the
pointer type, making allocation size and pointer stride provably
consistent regardless of what len the firmware provides.

| An inefficient regular expression complexity issue in the in-memory query evaluation component of the Mongoid library may allow an unauthenticated party to cause excessive processing within an embedding application process. Applications that place user-supplied text into a pattern-matching query condition on an embedded association may become unresponsive. |
| Roo-Code through 3.54.0 contains an auto-approve bypass vulnerability in the shell command parsing logic that allows attackers to execute denied shell commands by exploiting the omission of the bash pipe operator from the command parser's operator token set. Attackers can craft a command line with an allowlisted prefix followed by the stderr-redirecting pipe operator and a denied command, causing the parser to approve the full pipeline while bash executes the denied component with the agent's auto-execute privileges on the developer's machine. |

fbdev: kyro: Validate overlay viewport coordinates
The overlay viewport end coordinates are computed from the viewport
origin and dimensions using 32-bit unsigned arithmetic. Large input
values can cause these calculations to wrap around before the resulting
coordinates are passed to SetOverlayViewPort().
SetOverlayViewPort() packs the viewport coordinates into 16-bit
register fields. The X coordinates are additionally adjusted by +2
and +1 before being written. Validate the coordinate calculations
for 32-bit wraparound and ensure that the adjusted coordinates fit
within their 16-bit register fields before calling
SetOverlayViewPort().

RDMA/srp: fix heap information leak on a truncated SRP_CRED_REQ
srp_recv_done() passes wc->byte_len to srp_process_rsp(). It passes
nothing to srp_process_cred_req() and srp_process_aer_req(), which read
fixed-size fields from the receive buffer without checking that those
fields were received.
The buffer size is max_ti_iu_len, which comes from the login response
and is not validated. A target that advertises 8 and then sends an
8-byte SRP_CRED_REQ makes the initiator read req->tag from beyond the
end of the buffer. req->tag is copied into the SRP_CRED_RSP and sent
back, so those bytes reach the target. SRP_AER_REQ behaves the same way
and also reads req->lun.
The leak is 8 bytes per response. max_ti_iu_len also decides which slab
cache the buffer comes from. With 8 the buffer is a kmalloc-8 object and
the read is entirely outside it:
BUG: KASAN: slab-out-of-bounds in srp_recv_done+0x172b/0x1aa0
Read of size 8 at addr ffff888104714da8 by task kworker/u8:3/50
which belongs to the cache kmalloc-8 of size 8
The buggy address is located 0 bytes to the right of
allocated 8-byte region [ffff888104714da0, ffff888104714da8)
Without KASAN the returned bytes are whatever is next in the slab. One
run returned ".strtab".
rsp->data[3] in srp_process_rsp() has the same problem: only
resp_data_len is checked before it is read.
Drop a request that is shorter than the structure being parsed, and
check byte_len before the tsk_mgmt read. |

ocfs2: validate external xattr entries when reading metadata
ocfs2_validate_xattr_block() checks the xattr block header before the
block reaches higher-level xattr users, but it does not verify that a
non-indexed block's xh_count and entry offsets fit inside the block.
Indexed buckets likewise reach list/get consumers after ECC without an
entry-bounds check.
Use the flat xattr entry validator for non-indexed external xattr blocks,
and use a bucket-specific validator for indexed buckets at metadata read
time. The bucket validator keeps the entry array bounded by the first
bucket block while checking name/value offsets against the bucket block
they target.
Reject corrupted external xattr metadata before listxattr() or getxattr()
can walk out-of-range entry arrays or name/value offsets.

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: don't force read-only on transient -EAGAIN from reloc merge
On a zoned FS, btrfs_delayed_refs_rsv_refill() returns -EAGAIN whenever
the over-committed metadata plus the zone_unusable bytes exceeds the
usable size in a metadata block-group to avoid heavy over-commit of
metadata and early ENOSPC in one transaction.
If this happens while doing reclaim, the transaction is getting aborted.
Treat -EAGAIN as a soft, retryable condition in case of block-group
reclaim. |

wifi: mt76: mt7996: fix out-of-bounds link array access in mt7996_tx()
When mac80211 leaves the link unspecified, mt7996_tx() substitutes the
primary link id of the station or vif. That value is
IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added,
and it is then used unchecked to index vif->link_conf[],
mvif->mt76.link[] and sta->link[], all of which hold
IEEE80211_MLD_MAX_NUM_LINKS (15) entries.
Clamp the primary link id to the default link before using it, and use
the clamped value for the link_sta fallback as well. |

wifi: mt76: mt7996: reserve space for the CSA-abort countdown TLV
When a CSA countdown is active, mt7996_mcu_beacon_cntdwn() emits two
bss_bcn_cntdwn_tlv entries (the CSA countdown and the CCA-abort BCC), but
MT7996_BEACON_UPDATE_SIZE only reserved one. With MBSSID enabled and a
near-maximum beacon template the extra 8 bytes could push the offload
command past MT7996_MAX_BSS_OFFLOAD_SIZE and trigger skb_over_panic().
Reserve room for both countdown TLVs. |

powerpc/syscall: Fix syscall skip handling for seccomp and ptrace
After enabling GENERIC_ENTRY on PowerPC, syscall_enter_from_user_mode()
returns -1 as a sentinel to signal that seccomp or ptrace has intercepted
the syscall and already set a return value via syscall_set_return_value().
system_call_exception() was not handling this sentinel, and since -1UL
is >= NR_syscalls, the code fell into the out-of-range path and returned
-ENOSYS, overwriting the errno already placed in regs->gpr[3].
The naive fix of checking r0 == -1L before the NR_syscalls bounds check
is ambiguous: a user legitimately calling syscall(-1) also produces r0 ==
-1L, and a tracer intercepting such a call would have its injected return
value silently discarded.
Fix this by introducing a thread flag that is set whenever
syscall_set_return_value() explicitly updates the return value. In
system_call_exception(), check and clear this flag before dispatching
the syscall, and return the preset value directly when it is present.
This ensures that an explicitly supplied return value always suppresses
syscall execution, regardless of the syscall number.
This handles all seccomp actions correctly:
- SECCOMP_RET_ERRNO, SECCOMP_RET_TRACE (no tracer), SECCOMP_RET_USER_NOTIF:
all call syscall_set_return_value(), flag is set, injected value returned.
- SECCOMP_RET_TRAP, SECCOMP_RET_KILL: call syscall_rollback() and deliver
a signal; flag is not set, but the process is dying so the return value
is irrelevant.
The fix covers both ppc32 and ppc64 with no #ifdefs. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix out-of-bounds access in mmio copy helpers
mt76_mmio_write_copy() and mt76_mmio_read_copy() iterate up to
ALIGN(len, 4), so a length that is not a multiple of four reads past the
source buffer (write_copy) or writes past the destination (read_copy).
Copy the aligned body in the loop and handle the remaining tail through a
4-byte bounce buffer, keeping the register access width unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss
If a peer's VHT/HE MCS map has no supported spatial stream (all fields
0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),
which was then written into the firmware sta_rec_bf beamforming fields.
Clamp the result to 0. |

drm/panthor: Add vm_bind region with kbo range overlap check
When a VM is created, caller has to specify the range of the address space
carve-out set aside for mapping kernel BO's. That means vm_bind mappings of
UM-exposed BO's should not intersect with that region, but at the moment
we're not checking this.
At first, I thought of giving these values to drm_gpuvm_init() through its
reserve_{offset, range} arguments, but it turns out that is meant for VM
address spans that are not managed through the usual drm_gpuvm split/merge
circuit, so storing the end of the user VA range at VM creation time and
doing a quick check in the vm_bind ioctl path was the simplest workaround.
The new check also makes sure vm_bind range doesn't overflow the size of a
64-bit unsigned integer. That was already being done further down the call
stack inside drm_gpuvm_sm_map -> drm_gpuvm_range_valid, but it's best to
fail early in the driver before GPUVM functions are invoked so that we
won't waste time allocating vm_bind context resources. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: debugfs: Reserve space for a string terminator
ufs_saved_err_write() copies user input into a zero-initialized stack
buffer and passes it to kstrtoint(). A write that fills the entire buffer
overwrites its only terminator.
Reject an input whose length leaves no room for the trailing NUL. |
