CVE-2026-64304

In the Linux kernel, CVE-2026-64304 affects the crypto qat driver: the RSA CRT component handling in qat_rsa_setkey_crt() can write out of bounds when a CRT component exceeds the allocated half-key buffer, causing memory corruption. The root cause is that the generic RSA key parser bounds compone...

CVE-2026-64293

CVE-2026-64293 affects the Linux kernel iommufd component. A 32-bit bound-check in iommufd_veventq_fops_read() uses sizeof(hdr) (size of the pointer) instead of sizeof(*hdr), causing under-count of the vEVENT header and potentially writing past the user buffer during header+data payload copy. Mul...
