CVE-2026-98087
The Linux kernel contains a vulnerability where the RT balancer enters a retry loop when handling migrate_disable() 'd Real-Time (RT) tasks. Because these tasks remain on the pushable list while being pinned, the scheduler repeatedly attempts to push them, fails, and falls back to pushing the cur...
CVE-2026-98085 bpf: backtrack_insn(): Handle ld_{abs,ind} subprog exit edge
In the Linux kernel, the following vulnerability has been resolved: bpf: backtrackinsn: Handle ldabs,ind subprog exit edge Nicholas Carlini reported a bug in precision backtracking mechanism for BPFLD | BPFIND,ABS instructions. These instructions are modelled as two branches: - fallthrough; -...

CVE-2026-98085
The Linux kernel contains a vulnerability in the BPF precision backtracking mechanism affecting BPF_LD | BPF_{IND,ABS} instructions. The root cause is that the backtrack_insn() function fails to handle the implicit exit case from a subprogram. Specifically, it does not call bt_subprog_enter() whe...
CVE-2026-98083 btrfs: fix transaction use-after-free in raid stripe insertion
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix transaction use-after-free in raid stripe insertion If allocation of a RAID stripe extent fails, btrfsinsertoneraidextent aborts and ends the transaction before returning -ENOMEM. btrfsfinishoneordered, the production...
EUVD-2026-86914
In the Linux kernel, the following vulnerability has been resolved: bpf: backtracking shouldn't clear outer frame R1-R5 for callbacks When processing calls to bpfloop verifier marks R1 and R4 as precise. R1 tracks loop iterations number and because of the 'callbackdepth R1' mechanics in...
CVE-2026-98084
The Linux kernel contains a vulnerability in the BPF verifier related to bpf_loop(). When processing callbacks, the verifier is intended to mark register R1 (which tracks loop iterations) as precise to satisfy callback_depth

CVE-2026-98083
The Linux kernel contains a use-after-free vulnerability within the btrfs filesystem during RAID stripe insertion. The root cause occurs when the allocation of a RAID stripe extent fails; the function btrfs_insert_one_raid_extent() aborts and ends the transaction before returning -ENOMEM. However...

CVE-2026-98081
A vulnerability exists in the Linux kernel 's btrfs filesystem involving the zoned feature. The root cause is that do_zone_finish() clears the BLOCK_GROUP_FLAG_ZONE_IS_ACTIVE flag but returns early if call_zone_finish() fails. This results in a reference leak for inactive block groups on fs_info-...

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix the possible bioclist memory leak during error There are two possible ways to leak bioc memory on btrfsorderedextent::bioclist: - An error occurred for btrfsinsertoneraidextent Then the function btrfsinsertraidextent...
CVE-2026-98082
The Linux kernel contains a memory leak vulnerability in the btrfs filesystem within btrfs_ordered_extent::bioc_list. The root cause involves bioc_list memory leaking during error conditions, specifically when btrfs_insert_one_raid_extent() fails or when an ordered extent encounters an IO error (...
