CVE-2026-68365

In the Linux kernel, the following vulnerability has been resolved: USB: serial: ioedgeport: cap received transmit credits The interrupt-status packet reports transmit credits returned by the device. edgeinterruptcallback adds the 16-bit value to txCredits without checking maxTxCredits. edgewrite...

CVE-2026-68365

The CVE concerns the Linux kernel USB serial driver for io_edgeport. The vulnerability arises because edge_interrupt_callback() adds a 16-bit transmit-credits value to txCredits without enforcing maxTxCredits. edge_write() then uses (txCredits − software FIFO count) as the data that fits, and sin...

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...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-68365

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - USB: serial: ioedgeport: cap received transmit credits The interrupt-status packet reports transmit credits returned by the device. edgeinterruptcallback adds t...

libaom: libaom: heap buffer overflow in AV1 encoder first-pass stats buffer via LAP mode

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...

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 =...

CVE-2026-64300 perf/aux: Fix page UAF in map_range()

In the Linux kernel, the following vulnerability has been resolved: perf/aux: Fix page UAF in maprange maprange reads rb-auxpages, rb-auxnrpages and rb-auxpgoff via perfmmaptopage while holding only event-mmapmutex. Those fields are serialized by rb-auxmutex, and mmapmutex is per event. Thus, two...

CVE-2026-64258 fuse-uring: remove request-less entries from ent_w_req_queue to fix NULL deref

In the Linux kernel, the following vulnerability has been resolved: fuse-uring: remove request-less entries from entwreqqueue to fix NULL deref If a copy into the userspace ring buffer fails, a request will be terminated and fuseuringreqend will set ent-fusereq to NULL but it will leave the entry...

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...

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...
