CVE-2026-68143

CVE-2026-68143 affects the Linux kernel SLIP path. A race between MTU changes and receive processing can occur because sl_realloc_bufs() updates rbuff and buffsize while holding sl->lock, but slip_receive_buf() may write to rbuff without the lock. An MTU change/shrink can expose the new smalle...

JLSEC-2026-957 ImageMagick Has Signed Integer Overflow in SIXEL Decoder, Leading to Memory Corruption

A signed integer overflow vulnerability in ImageMagick's SIXEL decoder allows an attacker to trigger memory corruption and denial of service when processing a maliciously crafted SIXEL image file. The vulnerability occurs during buffer reallocation operations where pointer arithmetic using signed...

kernel: tipc: fix double-free in tipc_buf_append()

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

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,...

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...
