SUSE CVE-2026-52972

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Cap AEAD AD length to 0x80000000 In order to prevent arithmetic overflows when checking the TX buffer size, cap the associated data length to 0x80000000...

CVE-2026-53171

The CVE affects the Linux kernel’s accel/ethosu driver. The dma_length() function can under- or overflow while deriving DMA region usage, causing region_size[] to be under-reported and potentially bypassing bounds checks in ethosu_job.c. The issue arises from arithmetic in len calculations, signe...
