CVSS v3.1 |
| Cpanel::JSON::XS versions from 4.28 before 4.80 for Perl leak the array collecting duplicate key values under dupkeys_as_arrayref in decode_hv.
With dupkeys_as_arrayref, the values of a duplicate object key are collected into a new array. An extra reference is never released, so the array and every value in it outlive the decoded structure. The array also leaks when decoding fails after a duplicate key.
Repeatedly decoding untrusted JSON with a duplicate key holding a large value exhausts process memory. |
| Missing release of memory after effective lifetime in Windows DHCP Client allows an unauthorized attacker to deny service over a network. |
| Cpanel::JSON::XS versions before 4.80 for Perl leak the decoded arguments of a tagged value when its THAW method dies in decode_tag.
With allow_tags, a tagged value's class name and argument array are decoded and passed to the class's THAW method. Both are released only after THAW returns, so a THAW that dies leaves the whole decoded argument structure allocated.
Each rejected document leaks data of a size the sender chooses, so a process that catches the error and keeps running exhausts its memory. |
| Cpanel::JSON::XS versions from 3.0202 before 4.80 for Perl leak memory and retain overloaded objects when encoding values as strings in encode_stringify.
encode_stringify writes a value in its string form under allow_stringify, under convert_blessed for objects without TO_JSON, and under allow_bignum. For an array or hash object with a "" overload, and from 4.20 a scalar object, it takes an extra reference that is never released, so the object and everything it references are never freed. From 4.10 it also never frees its copy of the string.
Repeatedly encoding data that contains such values grows process memory without bound. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the magick compare command caused by missing cleanup when an operation fails. Attackers can supply inputs that trigger repeated failed compare operations to exhaust memory and cause denial of service. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in PerlMagick that fails to free values returned when reading image properties. Attackers can repeatedly trigger property reads through five affected PerlMagick code locations to exhaust memory and cause denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak caused by a missing cleanup when the -set profile option is used. An attacker who induces a user to process images with the -set profile option can leak memory, potentially exhausting resources and causing a denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in its XML parsing code, where allocated memory is not released when parsing reaches the nesting depth limit. Attackers can supply crafted, deeply nested XML data to trigger the leak, causing memory exhaustion and denial of service. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the FPX encoder that allows attackers to exhaust memory by supplying a crafted image. Attackers can submit crafted images for FPX encoding to leak memory repeatedly, causing resource exhaustion and denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the MSL decoder that fails to release allocated memory when processing a crafted MSL image. Attackers can supply crafted MSL files for processing to repeatedly leak memory, causing resource exhaustion and denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix subreq ref leak
Fix a subrequest ref leak in netfs_unbuffered_write() in the event that
subreq->io_iter ends up zero length during preparation. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix kmap_local leak in write_mft_record_nolock() error paths
write_mft_record_nolock() maps the MFT record folio with
kmap_local_folio(), but the pre_write_mst_fixup() and
bio_add_folio() failure paths jump to the error label without
unmapping it. kmap_local mappings are stack-ordered per task, so
leaking one corrupts the nesting for any outer mapping.
Unmap the folio on those error paths too. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: put the chained BO when its mapping fails
amdxdna_cmd_set_error() looks up the first BO of a command chain, which
takes a reference, and drops it at the end of the function. The mapping of
that BO is established in between, and the failure path returns without the
put, so the reference is leaked.
Ordinary use does not reach it. The chain has been submitted before any of
this runs, so aie2_cmdlist_fill_slot() has already called
amdxdna_cmd_get_op() on that BO and amdxdna_gem_vmap() has cached its
address. What makes it reachable is that the BO is resolved again by
handle here, and the handle is userspace's to recycle: closing it after
submission and importing a dma-buf whose exporter implements no vmap onto
the same id leaves amdxdna_gem_get_obj() returning an object this cannot
map, since prime_import() types every import AMDXDNA_BO_SHARE. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the handling of the -cdl (color decision list) option, where allocated memory is not cleaned up after use. Attackers can supply input that causes the -cdl option to be processed, repeatedly leaking memory and degrading availability through resource exhaustion. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the handling of XMP profiles by various decoders. Attackers can supply images with a crafted XMP profile that leak memory each time they are processed, leading to resource exhaustion and denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the JNG encoder that fails to release allocated memory when processing a crafted image. Attackers can supply crafted images that are encoded to JNG to leak memory, potentially causing resource exhaustion and a limited denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: fix ntfs_mount_options leak in ntfs_fill_super()
In ntfs_fill_super(), the fc->fs_private pointer is set to NULL without
first freeing the memory it points to. This causes the subsequent call to
ntfs_fs_free() to skip freeing the ntfs_mount_options structure.
This results in a kmemleak report:
unreferenced object 0xff1100015378b800 (size 32):

entry_SYSCALL_64_after_hwframe+0x76/0x7e
This issue can be reproduced using the following commands:
fallocate -l 100M test.file
mount test.file /tmp/test
Since sbi->options is duplicated from fc->fs_private and does not
directly use the memory allocated for fs_private, it is unnecessary to
set fc->fs_private to NULL.
Additionally, this patch simplifies the code by utilizing the helper
function put_mount_options() instead of open-coding the cleanup logic. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the MAT decoder that fails to release allocated memory in a specific error path. Attackers can supply crafted MAT files that trigger this error path repeatedly, causing small memory leaks that gradually consume process memory. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: fix XSK buffer leak on error descriptor
When the error bit is set in the RX completion descriptor, the buf_state
and its attached buffer should be freed. In the case of AF_XDP ZC, the
XSK buffer was not freed, leading to a leak.
This issue was caught by LLM. |
| MessagePack is the serializer implementation for Python msgpack.org. Prior to 1.2.3, the msgpack-python C extension (msgpack._cmsgpack) leaks a decoded map value when deserialization rejects a key with strict_map_key=True (the default). Repeated malformed inputs can cause unbounded process memory growth and denial of service in applications that deserialize attacker-controlled MessagePack data. Both unpackb() and the streaming Unpacker API are affected. The pure-Python fallback does not exhibit this leak in the reported tests. This issue is fixed in version 1.2.3. |
