CVE-2026-49417
The FreeBSD sound(4) driver contains a memory-safety error in its mmap(2) support. Specifically, the audio buffer backing a mapping can be freed when the device is closed while the mapping remains valid. This allows the freed memory to be reused elsewhere while still accessible through the stale ...
CVE-2026-49417 Multiple vulnerabilities in the sound(4) mmap path
Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...
CVE-2026-38641

kernel: selinux: fix overlayfs mmap() and mprotect() access checks
A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...
