In the Linux kernel, the following vulnerability has been resolved: btrfs: do not force reloc root creation during qgroupaccountsnapshot BUG When running btrfs/252 with quota enabled through MKFSOPTIONS="-O quota", it has a high chance to trigger the following kernel warning and flips the fs RO:...

CVE-2026-98080

The Linux kernel contains a vulnerability in the btrfs filesystem where triggering qgroup_account_snapshot() while quotas are enabled (via MKFS_OPTIONS="-O quota") can cause a kernel warning and flip the filesystem to read-only (RO) . The root cause is a tree reference to a metadata extent that n...

CVE-2026-98078 ipvs: fix reversed sequence option serialization

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix reversed sequence option serialization htonseq expects the host-order source first and the unaligned network-order destination second. The version 1 sync sender passes these arguments in reverse for both sequence blocks...

CVE-2026-98079

The Linux kernel contains a concurrency issue in the btrfs: zstd component where a writer can sleep indefinitely in zstd_get_workspace(). The root cause is a lost wakeup occurring because zstd_alloc_workspace() fails and the task queues unconditionally on zwsm->wait without re-testing the pool...

CVE-2026-98078

The Linux kernel contains a vulnerability in the ipvs component related to incorrect sequence option serialization. The hton_seq() function expects host-order source and network-order destination arguments, but the version 1 sync sender passes these arguments in reverse. This flaw leaves 24 bytes...

CVE-2026-98076 tracing/probes: Fix use-after-free on field name/type of events with multiple probes

In the Linux kernel, the following vulnerability has been resolved: tracing/probes: Fix use-after-free on field name/type of events with multiple probes The fields of a probe-based dynamic event kprobe, uprobe, eprobe and fprobe events are created in traceprobedefineargfields by handing the...

CVE-2026-98077 netfilter: nf_conntrack_sip: fix OOB read in sip_skip_whitespace()

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntracksip: fix OOB read in sipskipwhitespace sipskipwhitespace returns dptr unchanged when its own loop exhausts the buffer dptr == limit, instead of NULL like its sibling sipfollowcontinuation returns on its own...

CVE-2026-98076

The Linux kernel is vulnerable to a use-after-free issue in the tracing/probes component. The root cause resides in traceprobe_define_arg_fields(), which stores pointers to probe argument name/type strings without copying them. When multiple probes share a dynamic event (kprobe, uprobe, eprobe, o...

CVE-2026-98077

The Linux kernel contains an out-of-bounds (OOB) read vulnerability in the netfilter: nf_conntrack_sip component. The root cause is located in the sip_skip_whitespace() function, which fails to return NULL when its loop exhausts the buffer (where dptr == limit). Because the calling function ct_si...

CVE-2026-98075

The Linux kernel contains a vulnerability where the fixups.c:jit_subprogs() function fails to rewrite BPF_PSEUDO_FUNC loads for the main program when env->subprog_cnt is not greater than 1. This allows a program to reference the main function as a callback (e.g., via bpf_timer_set_callback()),...
