CVE-2026-52993 tipc: fix double-free in tipc_buf_append()

In the Linux kernel, the following vulnerability has been resolved: tipc: fix double-free in tipcbufappend tipcmsgvalidate can potentially reallocate the skb it is validating, freeing the old one. In tipcbufappend, it was being called with a pointer to a local variable which was a copy of the...

CVE-2026-52993

Summary (CVE-2026-52993): In the Linux kernel TIPC module, a double-free flaw occurs in tipc_buf_append() when tipc_msg_validate() reallocates an skb and the code incorrectly frees the original skb. The root cause is that the validation path may free a previously freed skb if reallocation occurs,...

Astra Linux – Vulnerability in expat

In libexpat before version 2.7.4, the doContent function does not properly determine the buffer size bufSize, as there is no check for integer overflow during the reallocation of the tag buffer...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in yuvensurebuffer in libfreerdp/codec/h264.c, h264-width and h264-height were updated before the reallocation loop. If any winpralignedrecalloc call fails, the function returns FALSE, but width/height have...

SUSE CVE-2026-56132

In libexpat before 2.8.2, there is a heap-based buffer overflow in doProlog in xmlparse.c because scaffold backing array reallocation is mishandled when there is data-structure sharing across parsers...

CVE-2026-12706

A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decodemove function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by...
