Descripción técnica

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Also unshare DATA/RESPONSE packets when paged frags are present The DATA-packet handler in rxrpc_input_call_event() and the RESPONSE handler in rxrpc_verify_response() copy the skb to a linear one before calling into the security ops only when skb_cloned() is true. An skb that is not cloned but still carries externally-owned paged fragments (e.g. SKBFL_SHARED_FRAG set by splice() into a UDP socket via __ip_append_data, or a chained skb_has_frag_list()) falls through to the in-place decryption path, which binds the frag pages directly into the AEAD/skcipher SGL via skb_to_sgvec(). Extend the gate to also unshare when skb_has_frag_list() or skb_has_shared_frag() is true. This catches the splice-loopback vector and other externally-shared frag sources while preserving the zero-copy fast path for skbs whose frags are kernel-private (e.g. NIC page_pool RX, GRO). The OOM/trace handling already in place is reused.

——0A weakness has been identified in D-Link DSM-G600 1.01. This affects an unknown function of the file /load_file.cgi of the component Multipart Handler. Executing a manipulation can lead to out-of-bounds write. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.4h CVE-2026-58106—

——1CVE-2025-40843 https://github.com/advisories/GHSA-5xf2-f6ch-6p8r was fixed by replacing unchecked strcpy() with a bounded safe_strcpy() helper. At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size passed down is the full PATH_MAX. safe_strcpy() is strncpy(), which NUL-pads the destination out to the whole n, so this site writes 4096 bytes into the 4094 that remain — a 2-byte stack overflow on every invocation, independent of the input path's length. This issue affects CodeChecker: through 6.28.2.3d CVE-2026-183935.4 MED

——5A flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond the bounds of a heap-allocated buffer when processing crafted TDSC cursor data. A remote attacker could exploit this by supplying a specially crafted video file, potentially leading to a denial of service or arbitrary code execution.3d CVE-2026-78011—
