GHSA-7CG4-MP48-CGGR
Vulnerability from github – Published: 2024-03-25 09:32 – Updated: 2025-03-13 21:31In the Linux kernel, the following vulnerability has been resolved:
net: zero-initialize tc skb extension on allocation
Function skb_ext_add() doesn't initialize created skb extension with any value and leaves it up to the user. However, since extension of type TC_SKB_EXT originally contained only single value tc_skb_ext->chain its users used to just assign the chain value without setting whole extension memory to zero first. This assumption changed when TC_SKB_EXT extension was extended with additional fields but not all users were updated to initialize the new fields which leads to use of uninitialized memory afterwards.

GHSA-7HFV-J3WG-PJ3F
Vulnerability from github – Published: 2026-07-25 12:31 – Updated: 2026-09-04 18:31In the Linux kernel, the following vulnerability has been resolved:
hfs/hfsplus: zero-initialize buffer in hfs_bnode_read
hfs_bnode_read() can return early without writing to the output buffer when is_bnode_offset_valid() fails or when check_and_correct_requested_ length() corrects the length to zero. Callers such as hfs_bnode_read_ u16() and hfs_bnode_read_u8() pass stack-allocated buffers and use the result unconditionally, leading to KMSAN uninit-value reports.
Rather than initializing at each individual call site, zero the buffer at the start of hfs_bnode_read() before any validation checks. This ensures all callers in both hfs and hfsplus get a deterministic zero value regardless of which early-return path is taken.

GHSA-7MRQ-J773-6867
Vulnerability from github – Published: 2026-08-07 00:31 – Updated: 2026-08-07 18:31FFmpeg versions from 3.0 up to, but not including, 9.0 contain an uninitialized heap memory read vulnerability in the native Screenpresso decoder (libavcodec/screenpresso.c) that allows attackers to recover sensitive memory contents by supplying a crafted SPV1 packet with a valid zlib stream that decompresses fewer bytes than the full frame requires. The screenpresso_decode_frame() function fails to validate the produced byte count before calling av_image_copy_plane() to copy the complete frame dimensions from the persistent ctx->inflated_buf buffer, causing unwritten heap memory from prior allocations or prior frames to be copied into decoded output and potentially exposing sensitive data such as userspace addresses from persistent decoding services.

Mitigation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
