CVE-2026-74580

A flaw was found in the Linux kernel's vhost subsystem. A local attacker could exploit this vulnerability by reconfiguring a virtual ring vring using specific ioctl commands while a device Input/Output Memory Management Unit IOTLB is attached. This improper handling of the vring metadata cache ca...

CVE-2026-74583

A flaw was found in the Linux kernel's net/sched: clsroute component. A race condition exists in the route4 classifier's fastmap cache, where a reader can re-cache a pointer to a filter that has already been freed by a writer. This can lead to a use-after-free condition, allowing subsequent packe...

CVE-2026-74582

A flaw was found in the Linux kernel's packet handling functions, specifically packetsnd and packetsendmsgspkt. This vulnerability arises from inconsistent handling of network device header lengths during packet construction. A local attacker could exploit this by triggering a race condition duri...

CVE-2026-74581

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

AZL-96998 CVE-2026-74583 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: fix fastmap use-after-free on filter The route4 classifier maintains a 16-slot fastmap cache that stores raw struct route4filter pointers indexed by id, iif. The reader route4classify populates this cache via...

CVE-2026-74582

In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hardheaderlen in non-ring send paths packetsnd reads dev-hardheaderlen multiple times while allocating and constructing an skb.

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: clear suppressed fib6 rule result fib6rulesuppress drops a suppressed route with ip6rtputflags, but leaves res-rt6 pointing at the released rt6info. If no later rule supplies a replacement, fib6rulelookup still sees...

CVE-2026-74580

In the Linux kernel, the following vulnerability has been resolved: vhost: reset the vring metadata cache on vring reconfiguration vq-metaiotlb caches the vhostiotlbmap that backs each vring metadata region, and iotlbaccessok returns early on a cache hit, taking the hit as proof that the region h...
