CVE-2026-43266 EFI/CPER: don't go past the ARM processor CPER record buffer

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't go past the ARM processor CPER record buffer There's a logic inside GHES/CPER to detect if the sectionlength is too small, but it doesn't detect if it is too big. Currently, if the firmware receives an ARM process...

CVE-2026-43266

The CVE-2026-43266 issue affects the Linux kernel’s ARM CPER/APEI handling: a CPER record with an oversized section_length can cause the kernel to read beyond the intended firmware buffer, leading to a large data dump and potential memory access issues. The fix adds a guard so the kernel stops at...

CVE-2026-43254

CVE-2026-43254: Linux kernel openvpn TCP stream handling corrected. Ovpn_tcp_recv now allocates a separate skb per packet and uses skb_copy_bits to copy only the packet payload, skipping the 2-byte length prefix; length checks guard allocation to prevent invalid skbs. This resolves header offset ...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodechoice In decodechoice, the boundary check before getlen uses the variable len, which is still 0 from its initialization at the top of the function: unsigned int type, ext, len = ...

CVE-2026-43210

The CVE-2026-43210 entry concerns the Linux kernel tracing ring-buffer subsystem. The root cause is inadequate validation of event length in rb_read_data_buffer(), which can cause an invalid memory access if an event’s length is corrupted, potentially at boot time. The published fix is to check t...
