CVE-2026-72492
A flaw was found in ksmbd, the in-kernel SMB3 server for Linux. This memory corruption vulnerability, known as a use-after-free, occurs when the system attempts to use memory after it has been released. A remote attacker could trigger this by performing a concurrent close operation during lease...
CVE-2026-49428
Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...
CVE-2026-49427
Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. An unprivileged local user can abuse the bug to...
CVE-2026-49422
The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...
CVE-2026-49428 posixshm: system calls can incorrectly free memory of largepage objects
Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...
CVE-2026-49428
In FreeBSD's posixshm module, open(2) with O_TRUNC and fspacectl(2) failed to verify whether operations are permitted on largepage objects, incorrectly freeing kernel memory. An unprivileged local user can read freed kernel memory and escalate privileges. Affected: all supported versions prior to...

CVE-2026-49427
CVE-2026-49427 is a use-after-free vulnerability in FreeBSD's POSIX largepage shared memory objects (posixshm module). Pages in largepage objects were not explicitly wired, so when sendfile(2) transmitted such an object with the SF_NOCACHE flag, it freed underlying pages while existing mappings s...
CVE-2026-49422
The FreeBSD advisory (FreeBSD-SA-26:43.tcp) confirms the bug affects all supported FreeBSD versions and provides specific correction commit hashes for stable/15, releng/15.1, releng/15.0, stable/14, releng/14.4, and releng/14.3 branches, all dated 2026-06-30. Workarounds include not loading tcp_r...

The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...
CVE-2026-49422 Use-after-free in TCP RACK stack option handler
The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...

CVE-2026-49418
When msyncMSINVALIDATE is called on a mapping of an unmanaged device object, the physical pages in the mapping range are marked invalid but remain in the pager's page list. A subsequent page fault will cause the fault handler to re-insert the page into the object's list. This corrupts the list, a...
CVE-2026-72321
A flaw was found in the Linux kernel's IPv4 Internet Group Management Protocol IGMP component. Incorrect handling of reference counts in the igmpmodtimer and igmpstoptimer functions can occur when a multicast list entry is concurrently removed. This can lead to a memory leak of the im structure,...
