CVE-2026-64258

A flaw was found in the fuse-uring component of the Linux kernel. When a copy operation to the userspace ring buffer fails, a request can be terminated improperly, leading to a NULL pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial...

CVE-2026-64300

A flaw was found in the Linux kernel's perf/aux subsystem. A use-after-free UAF vulnerability exists in the maprange function due to a race condition. This can occur when two performance events share a ring buffer, allowing a local attacker to map a memory page that has already been freed...

CVE-2026-64464

Consolidated details show CVE-2026-64464 affects the Linux kernel xhci sideband path: xhci_ring_to_sgtable() allocates a temporary pages array used to build an sg_table via sg_alloc_table_from_pages(). On success, the temporary array isn’t freed, causing a leak each time a sideband client uses an...

CVE-2026-64402 coresight: ultrasoc-smb: Fix OOB write in smb_sync_perf_buffer()

In the Linux kernel, the following vulnerability has been resolved: coresight: ultrasoc-smb: Fix OOB write in smbsyncperfbuffer When the SMB sink is used as a perf AUX sink, smbupdatebuffer calls smbsyncperfbuffer to copy hardware trace data into the perf AUX ring buffer pages. It derives pgidx =...

EUVD-2026-46379

Data::RingBuffer::Shared versions before 0.04 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in ring.h with openpath, ORDWR|OCREAT, 0666. The mode is 0666, so under the default umask 022 the file is created mode 0644 world-readabl...

EUVD-2026-46365

Data::RingBuffer::Shared versions before 0.04 for Perl allow a stack buffer overflow via an unvalidated elemsize in ringreadseq. The attach-time validator ringvalidateheader checks the capacity-overflow and totalsize consistency of the header but never caps elemsize against the destination size...

CVE-2026-59144

Data::RingBuffer::Shared versions before 0.04 for Perl allow a stack buffer overflow via an unvalidated elemsize in ringreadseq. The attach-time validator ringvalidateheader checks the capacity-overflow and totalsize consistency of the header but never caps elemsize against the destination size...

CVE-2026-59144

Data::RingBuffer::Shared prior to v0.04 for Perl has a stack-buffer overflow: ring_read_seq copies elem_size bytes into an 8-byte destination without capping elem_size, allowing a file-writable header to cause overflow and stack corruption. The attach-time header validation does not cap elem_size...

CVE-2026-64055 net: ethernet: cortina: Carry over frag counter

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Carry over frag counter The gmacrx NAPI poll function assembles packets in an SKB from a ring buffer. If the ring buffer gets completely emptied during a poll cycle, we exit gmacrx, but the packet is not y...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Ensuring that pending IRQ work is processed before freeing the ring buffer. A race condition was addressed in this fix, where irqwork could be queued in bpfringbufcommit, but the ring buffer was freed before the work execute...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Tracing: Ring-buffer: A fix was made to check the length of events before using them. Check the length of events before adding them for accessing the next index in rbreaddatabuffer. Since this function is used to validate possibl...

CVE-2026-56208

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Sync-IRQ works before the buffer is destroyed. If something was written to the buffer just before its destruction, it may be possible—though not in a real system—to destroy the ringbuffer before the IRQ-related...

Astra Linux – Vulnerability in Linux, Linux 5.10

It was discovered that there was a lack of CPU resources in the Linux kernel tracing module functionality in versions prior to 5.14-rc3. This issue occurred due to the way users utilize the trace ring buffer. Only privileged local users with the CAPSYSADMIN capability could exploit this flaw to...
