CVE-2026-98587 firewire: cdev: fix back-transition for iso_resource_auto client resource

In the Linux kernel, the following vulnerability has been resolved: firewire: cdev: fix back-transition for isoresourceauto client resource The todo member of isoresourceauto structure represents the state of the client resource and normally transitions in the following order: ISORESAUTOALLOC -...

CVE-2026-98587

The Linux kernel contains a vulnerability in the firewire driver related to the iso_resource_auto structure. Concurrent access between a work item and the file descriptor release function can trigger an invalid backward state transition from ISO_RES_AUTO_DEALLOC to ISO_RES_AUTO_REALLOC. The issue...

CVE-2026-98588

The Linux kernel is vulnerable to an out-of-bounds write in the sockmap component. The root cause is that sock_map_alloc() fails to reject max_entries values greater than INT_MAX, while sock_map_free() uses a signed integer iterator to traverse the sks[] array. When a SOCKMAP is created with max_...

CVE-2026-98588 bpf, sockmap: Reject max_entries > INT_MAX in sock_map_alloc

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Reject maxentries INTMAX in sockmapalloc sockmapalloc only rejects maxentries == 0 and otherwise allows any u32 value. sockmapfree then walks the sks array with a signed int iterator: int i; for i = 0; i...

CVE-2026-98586 sctp: hold asoc or transport before mod_timer() in timer handlers

In the Linux kernel, the following vulnerability has been resolved: sctp: hold asoc or transport before modtimer in timer handlers Take the association or transport reference before rearming a timer in the timer handlers. The existing code calls modtimer before taking the reference needed by the...

CVE-2026-98586 sctp: hold asoc or transport before mod_timer() in timer handlers

In the Linux kernel, the following vulnerability has been resolved: sctp: hold asoc or transport before modtimer in timer handlers Take the association or transport reference before rearming a timer in the timer handlers. The existing code calls modtimer before taking the reference needed by the...

CVE-2026-98586

A vulnerability exists in the Linux kernel SCTP implementation where the code calls mod_timer() before acquiring the necessary reference for a rearmed timer without holding the sock lock . This creates a race condition during timer cleanup: if a timer is deleted after mod_timer() returns but befo...

CVE-2026-98585 eth: fbnic: Avoid rounding zero ring sizes

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Avoid rounding zero ring sizes rounduppowoftwo is undefined for zero. ethtool permits a zero ring size to reach the driver, where the minimum-size check should reject it. Leave zero unchanged while rounding nonzero ri...

Leave zero unchanged while rounding nonzero ri...

CVE-2026-98585

The Linux kernel contains a vulnerability in the eth: fbnic driver related to how ring sizes are handled. The issue stems from the roundup_pow_of_two() function being undefined for zero, while ethtool allows a zero ring size to reach the driver. The fix involves leaving zero unchanged during roun...

CVE-2026-98584

The Linux kernel contains a potential stack information leak within the net/sched component. The em_text_dump() function allocates struct tcf_em_text on the stack without zeroing it. Because strscpy() was used instead of strncpy(), the remaining bytes of the structure remain uninitialized. These ...
