CVE-2026-98547

The Linux kernel is vulnerable to an integer overflow in the prb_calc_retire_blk_tmo() function within the af_packet component. The vulnerability occurs because the function performs 32-bit arithmetic when calculating mbits. A user-controlled tp_block_size (e.g., 256MiB) can cause the calculation...

In the Linux kernel, the following vulnerability has been resolved: arm64/boot: Disable trapping of PMZREL0 writes to EL2 initel2fgt2 writes one mask to both HDFGRTR2EL2 and HDFGWTR2EL2. PMZREL0 is write-only, so its trap bit, nPMZREL0, exists only in HDFGWTR2EL2 and is therefore never set: a...

CVE-2026-98546

The Linux kernel is affected by a vulnerability in the arm64/boot component. The root cause is located in __init_el2_fgt2(), which incorrectly writes a single mask to both HDFGRTR2_EL2 and HDFGWTR2_EL2 . Because PMZR_EL0 is write-only, its trap bit (nPMZR_EL0 ) is never set, causing a PMZR_EL0 wr...
