CVE-2026-64082

The CVE-2026-64082 issue affects the Linux kernel on riscv where uninitialized cregs data could be written to a task’s pt_regs during error paths. Specifically, compat_riscv_gpr_set() and compat_restore_sigcontext() call cregs_to_regs() unconditionally, even when user_regset_copyin() or __copy_fr...

CVE-2026-64006 netfilter: nf_tables: fix dst corruption in same register operation

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: fix dst corruption in same register operation For lshift and rshift, the shift operations are performed in a loop over 32-bit words. The loop calculates the shifted value and write it to dst, and then...

CVE-2026-64006

The CVE affects Linux kernel netfilter nf_tables. A dst corruption in the same-register operation occurred during shift (lshift/rshift) when src and dst pointed to the same memory location: the carry for the next iteration was read from the dst (modified) instead of the original src. The fix cach...

CVE-2026-63941

CVE-2026-63941 documents a Linux kernel KVM arm64 issue where ZCR_EL2 updates from a guest hypervisor could bypass proper masking, allowing L2 guests to observe VL values they shouldn’t. The fix moves the VL capping into restore points so the HW is always programmed with a capped value, regardles...
