CVE-2026-54369

The CVE-2026-54369 entry concerns acl before version 2.4.0, where a symlink traversal vulnerability exists in the libacl pathname-based functions acl_get_file(), acl_set_file(), acl_extended_file(), and acl_delete_def_file(). The underlying issue allows a local attacker to escalate privileges by ...

CVE-2026-22078 O+ Connect's lack of authentication for IPC channels led to a local privilege escalation vulnerability.

Because O+ Connect's IPC service does not authenticate clients, external applications can escalate privileges and perform sensitive actions through the IPC channel...

CVE-2026-22078

CVE-2026-22078 concerns O+ Connect where an unauthenticated IPC service allows a local attacker to escalate privileges via the IPC channel. The root cause is lack of client authentication on the IPC interface, enabling external applications to perform sensitive actions with elevated privileges. T...

CVE-2026-49416

The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An...

CVE-2026-49416

The CVE-2026-49416 issue affects FreeBSD vt(4) CONS_HISTORY: the ioctl handler validates the requested history size, but large values trigger an integer overflow in the buffer size calculation, causing a smaller heap allocation and an out-of-bounds write on initialization. This can enable an unpr...

CVE-2026-49412 Use-after-free bug in the IPV6_MSFILTER socket option handler

The kernel handler for IPV6MSFILTER dropped a serializing lock in order to copy the source-filter list from userspace, then reacquired the lock. During this window another thread could free the multicast filter structure, leaving the handler with a stale pointer to freed memory. An unprivileged...

CVE-2026-49412

The CVE-2026-49412 issue affects FreeBSD’s IPv6_MSFILTER in the kernel: the handler drops a serializing lock to copy the source-filter list and later reacquires it, creating a window where another thread can free the multicast filter structure and leave a stale pointer. This use-after-free enable...

CVE-2026-45258

dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

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-2026-53185

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...
