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...

CVE-2026-98545 ata: libata-scsi: bound the ATA passthru sense descriptor writes

In the Linux kernel, the following vulnerability has been resolved: ata: libata-scsi: bound the ATA passthru sense descriptor writes When an ATA PASS-THROUGH command to an ATAPI device fails, the sense buffer holds the device's REQUEST SENSE reply, and atascsisetpassthrusensefields trusts its...

CVE-2026-98545

The Linux kernel is vulnerable to an out-of-bounds read and write in the libata-scsi component. Specifically, when an ATA PASS-THROUGH command to an ATAPI device fails, the ata_scsi_set_passthru_sense_fields() function incorrectly trusts the additional length byte (sb[7] ) of the REQUEST SENSE re...

CVE-2026-98544

The Linux kernel contains a vulnerability where the bnad_pci_remove() and probe disable_ioceth paths fail to properly handle the iocpf_timer . While other timers are removed via timer_delete_sync() , the iocpf_timer remains active, leading bnad_iocpf_timeout() to attempt to take the bnad->bna_...

CVE-2026-98543

A flaw in the Linux kernel BPF subsystem allows a local privileged user to cause a Denial of Service (DoS) or file system corruption . The issue stems from improper locking where the kernel verifier incorrectly assumes an inode lock is held during certain file removal hooks (path_unlink and path_...

CVE-2026-98541

The Linux kernel contains a vulnerability where omitting the FOU_ATTR_IPPROTO attribute when sending a FOU_CMD_ADD request with FOU_ENCAP_DIRECT causes fou_create() to initialize the protocol to 0. Because fou_udp_recv() returns 0 when the protocol is 0, it informs the UDP tunnel layer that the s...
