CVE-2026-89545

A flaw was found in the Linux kernel. This vulnerability exists within the sunrpc component, where memory associated with rqargp and rqresp is freed prematurely. Specifically, the svcrqstfree function frees these structures synchronously, while the main request structure rqstp is freed later via...

CVE-2026-89682

A flaw was found in the Linux kernel's NFS daemon nfsd component. The nfsdfiledisposelistdelayed function, responsible for deferring file disposal, uses a separately allocated structure for its freeme queue. During network namespace teardown, this structure can be prematurely freed. This allows...

CVE-2026-89760 mm, swap: don't free a hibernation slot that is in the swap cache

In the Linux kernel, the following vulnerability has been resolved: mm, swap: don't free a hibernation slot that is in the swap cache A slot with a folio in the swap cache is freed when the folio leaves the cache, not when its count drops. swapputentriescluster follows that rule...

CVE-2026-80862

This Linux kernel vulnerability affects the nvme-tcp subsystem. The page_frag_cache is used to preallocate PDU buffers for preallocated block device requests, but since block devices are created in parallel threads, the cache is accessed in a thread-unsafe manner. This leads to incorrect refcount...

EUVD-2026-71312

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: fix usage of pagefragcache nvme uses pagefragcache to preallocate PDU for each preallocated request of block device. Block devices are created in parallel threads, consequently pagefragcache is used in not thread-safe...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...
