CVE-2026-45838

In the Linux kernel, the following vulnerability has been resolved: bpf: fix end-of-list detection in cgroupstoragegetnextkey listnextentry never returns NULL -- when the current element is the last entry it wraps to the list head via containerof. The subsequent NULL check is therefore dead code...

CVE-2026-46000

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix conn-level packet handling to unshare RESPONSE packets The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the skbuff may be shared with a packet sniffer, which would lead to...

CVE-2026-45967

In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The mapdirectvalueaddr function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolvepseudoldimm64...
