CVE-2026-68445
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Prevent shader BO mappings from becoming writable vc4gemobjectmmap rejects a writable mapping of a validated shader BO, but leaves VMMAYWRITE set. Userspace can map the BO read-only and then turn it writable with mprotec...
CVE-2026-68445
The Linux kernel vc4 driver fixed a vulnerability where a validated shader buffer object (BO) could be mapped read-only and later upgraded to writable via mprotect, bypassing the shader validator. The patch clears VM_MAYWRITE on the read-only mapping to prevent upgrades, aligning behavior with i9...

CVE-2024-53096
CVE-2024-53096: Linux kernel patch resolves faulty mmap_region() error path. Key changes move core logic into __mmap_region(), perform upfront validations, and unwind writable/ seal checks earlier. Effects include preallocating iterator state before file-backed hooks, early handling of mapping_ma...

ASB-A-200284993
In jitmemoryregion.cc, there is a possible bypass of memory restrictions due to a logic error in the code. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation...
