kernel: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

A flaw was found in the Linux kernel's RDMA/mana component. A local user could trigger a kernel corruption by providing specific configurations through the user Application Programming Interface uAPI that cause an internal error. This issue arises when Work Queues WQs are specified to share the...

kernel: nvmet-tcp: fix race between ICReq handling and queue teardown

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...

CVE-2026-52984

A flaw was found in the Linux kernel's networking scheduler netem. The queue limit check in the netemenqueue function does not properly account for reordered packets, allowing the total queue occupancy to exceed its configured limit. This oversight can lead to a Denial of Service DoS condition,...

CVE-2026-52976

A flaw was found in the Linux kernel. Specifically, within the drm/xe graphics driver, two error handling issues in the xeexecqueuecreateioctl function could lead to memory corruption. This could result in a dangling pointer or a use-after-free vulnerability. A local attacker could potentially...

CVE-2026-53242

In the Linux kernel, the following vulnerability has been resolved: ALSA: PCM: Fix wait queue list corruption in sndpcmdrain on linked streams sndpcmdrain uses initwaitqueueentry which does not clear entry.prev/next, and addwaitqueue with a conditional removewaitqueue that is skipped when tocheck...

CVE-2026-53223

In the Linux kernel, the following vulnerability has been resolved: net: guard timestamp cmsgs to real error queue skbs skbiserrqueue treats PACKETOUTGOING as the sole marker for an skb from skerrorqueue. That assumption is not true for AFPACKET sockets: outgoing packet taps are also delivered to...

CVE-2026-53175

In the Linux kernel, the following vulnerability has been resolved: inet: frags: fix use-after-free caused by the fqdirpreexit flush On netns teardown, fqdirpreexit walks the fqdir rhashtable and flushes every fragment queue that is not yet complete using inetfragqueueflush. That helper frees all...
