In the Linux kernel, the following vulnerability has been resolved: bpf: Fix UAF in sock clone early bailouts Similar to recent commit 9b51a6155d14 "bpf,fork: wipe -bpfstorage before bailouts that access it", skclone performs an initial shallow copy of the socket field -skbpfstorage via sockcopy...

CVE-2026-68391

CVE-2026-68391 affects the Linux kernel Bluetooth management path, specifically the mgmt_pending_cmds handling of hci_conn references. The issue is a Use-After-Free risk from dereferencing RCU-protected pointers outside critical sections and from using hci_conn in hci_sync callbacks without holdi...

CVE-2026-68386

The CVE concerns the Linux kernel’s BPF sockmap path. It describes a vulnerability where unhashed UDP sockets accepted by sockmap can have their refcount incremented via a BPF lookup, and if the socket becomes bound, the subsequent bpf_sk_release() may skip decreasing the refcount, leading to a m...

EUVD-2026-55572

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Reject unhashed UDP sockets on sockmap update UDP sockets get SOCKRCUFREE set when auto-bound. This means skisrefcountedunbound = true, while skisrefcountedbound = false. Because sockmap accepts unbound UDP sockets,...

CVE-2026-68322

CVE-2026-68322 concerns the Linux kernel RDS subsystem. When IPv6 is explicitly disabled with ipv6.disable=1, inet6_addr_lst is never initialized, because inet6_init() exits before addrconf_init() runs. This leads to a NULL dereference in __ipv6_chk_addr_and_flags() when attempting to bind an RDS...
