EUVD-2026-62338
To retrieve the previous timer value, the kernel calls realtimergettime, which obtains the current time for the timer's clock. For a timer using CLOCKTAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized output buffer was copied to...
CVE-2026-58084 Kernel stack disclosure via timer_settime(2)
To retrieve the previous timer value, the kernel calls realtimergettime, which obtains the current time for the timer's clock. For a timer using CLOCKTAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized output buffer was copied to...
CVE-2026-49430
The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...
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-2026-49422
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
FreeBSD is vulnerable to a flaw in its posixshm module involving largepage shared memory objects. Specifically, certain system calls such as open(2) with the O_TRUNC flag and fspacectl(2) fail to verify that these operations are prohibited on largepage objects, leading to the incorrect freeing of...

EUVD-2026-62254
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-2026-49427
The FreeBSD kernel's posixshm module contains a vulnerability where pages belonging to largepage shared memory objects were not explicitly wired. When sendfile(2) transmits such an object with the SF_NOCACHE flag, it incorrectly frees the underlying pages while existing mappings still refer to th...
CVE-2026-49422
A use-after-free vulnerability exists in the tcp_rack.ko kernel module of FreeBSD operating systems. The RACK setsockopt(2) handler drops the connection lock to copy option data from userspace and reacquires it later; however, it fails to reload the pointer to the stack's per-connection control b...

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-2026-49419
When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...
CVE-2026-19942
The Atarim – AI Agency for WordPress: Edit Pages, Fix Code, Update Plugins, SEO & Client Feedback plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the AVCFAbilitiesMedia::register replace-media-file executecallback function in all versions ...
CVE-2026-72276
A flaw was found in the metronomefb framebuffer driver within the Linux kernel. This vulnerability occurs because memory allocated for page references is not properly released when an error occurs during initialization. A local attacker could potentially exploit this to cause a denial of service...

If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...
CVE-2026-49419
The FreeBSD operating system (versions 15.0 and later ) is vulnerable to a prison reference count underflow in the kern_jail_set() and kern_jail_get() functions. When the JAIL_AT_DESC flag is used, the system incorrectly releases a reference to the caller's current prison before searching for the...
