In the Linux kernel, the following vulnerability has been resolved: fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal CXL is linked before fwctl in drivers/Makefile. Both use moduleinit, so cxlpcidriverinit runs first. When cxlpciprobe calls fwctlregister and then...

CVE-2026-53042

In CVE-2026-53042, the Linux kernel vulnerability stems from an initialization order: CXL is linked before fwctl in drivers/Makefile, causing fwctl_register to run before fwctl_init, so fwctl_class isn’t registered when device_add is called. This makes class_to_subsys() return NULL, skipping knod...

CVE-2026-53036 bpf, arm64: Fix off-by-one in check_imm signed range check

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Fix off-by-one in checkimm signed range check checkimmbits, imm is used in the arm64 BPF JIT to verify that a branch displacement in arm64 instruction units fits into the signed N-bit immediate field of a B, B.cond or...

CVE-2026-53036

The CVE-2026-53036 issue concerns the Linux kernel BPF JIT on ARM64. check_imm(bits, imm) erroneously allowed a signed N-bit range of [-2^N, 2^N), effectively giving an (N+1)-bit range, which permits values in [2^18, 2^19) for imm19 (and similarly for imm26) to slip through. This caused potential...
