CVE-2026-101302Remote DoS via receive-side kernel TLS

FreeBSD FreeBSD Veröffentlicht: (vor 19 Tagen)

Beschreibung

TLS 1.3 embeds the actual record type as the last non-zero byte of the decrypted payload, optionally followed by zero padding. The code which searches for the inner record type had an off-by-one bug which could be triggered by an invalid frame, leading to an underflow followed by an unconditional NULL pointer dereference, causing a kernel panic. A remote TLS 1.3 peer can send a specially crafted record to trigger a kernel panic, resulting in a Denial of Service (DoS).

Schwachstellentyp (CWE): CWE-193CWE-476

TOCTOU race between sound(4) buffer resizing and mmap

FreeBSD FreeBSD

When an audio channel's buffer needs to be resized, the sound(4) driver checks that the buffer is not memory-mapped and then drops the channel lock to allocate a new buffer. An mmap(2) call on another thread can complete during this window, after which the r…
