CVE-2026-80866
A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication subsystem. A busy-wait loop in the tipcexitnet function, intended to wait for UDP bearer cleanup, can consume excessive CPU cycles. This issue arises when the condresched function is ineffective, such as when a...
CVE-2026-93168
A flaw was found in the Linux kernel's dmaengine: xilinxdma component. When the xilinxdmapolltimeout function is called with a zero-value delay and an unfulfilled condition, the CPU can enter a prolonged busy-wait state. This occurs due to an underestimation of wall clock time, causing the system...
SUSE CVE-2026-98394
In the Linux kernel, the following vulnerability has been resolved: afunix: Return immediately when manageoob returns NULL for 0-length buffer. Fahad Alharbi reported that recv0, MSGPEEK triggers busy-wait in unixstreamreadgeneric if recv is blocking and the last skb in the queue is MSGOOB skb. I...
CVE-2026-98394
A flaw was found in the Linux kernel's UNIX domain socket afunix implementation. When a blocking receive operation is performed using a zero-length buffer and the peek flag on a socket where the last queued message contains out-of-band OOB data, the kernel fails to return properly. A local attack...

CVE-2026-98394
The Linux kernel contains a vulnerability in af_unix where recv(0, MSG_PEEK) triggers a busy-wait in unix_stream_read_generic(). This occurs when a blocking recv() is called and the final socket buffer (skb) in the queue is an MSG_OOB skb, but manage_oob() returns NULL for a 0-length buffer. The ...
