CVE-2026-64513

CVE-2026-64513 affects the Linux kernel KVM x86 path, where CR8 intercept is recomputed on PPR update. Root cause: after a patch to speed up TPR below-threshold vmexits, apic_update_ppr() can omit a deliverable interrupt, causing kvm_lapic_update_cr8_intercept() and vmx_update_cr8_intercept() to ...

In the Linux kernel, the following vulnerability has been resolved: 6lowpan: fix NHC entry use-after-free on error path lowpannhcdouncompression looks up an NHC descriptor while holding lowpannhclock. If the descriptor has no uncompress callback, the error path drops the lock before printing...

CVE-2026-64452

CVE-2026-64452 (Linux kernel 6LoWPAN) involves a race condition in 6LoWPAN’s Next Header Compression (NHC) handling that can cause a use-after-free in lowpan_nhc_do_uncompression when an NHC descriptor is freed while another path accesses nhc->name in an error path. The issue arises from holdi...

CVE-2026-64416

CVE-2026-64416 is a NULL pointer dereference in the Linux kernel's mm: swap_cgroup subsystem. lookup_swap_cgroup_id() passes swap_cgroup_ctrl[type].map to __swap_cgroup_id_lookup() without verifying the swap type was registered; on a swapless host , every ctrl->map is NULL, causing a crash. Th...

CVE-2026-64322

Mode C: Normal. The CVE-2026-64322 issue affects the Linux kernel UDF handling of sparing tables. The problem is that udf_load_sparable_map() validated reallocationTableLen as a byte count, while code walks the sparing table as an array of 8-byte entries, leading to potential out-of-bounds reads ...
