CVE-2026-98900

The Linux kernel contains a vulnerability in the xen/gntalloc component where the gntalloc_ioctl_alloc() function allocates the grant-id array before verifying if the requested count exceeds the global grant limit. This allows user-controlled allocations to reach kcalloc() even when they should b...

EUVD-2026-108855

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: mark the rcu locked areas properly When we bump the uref counter, there's no need to keep the rcu lock because the referred hash table can't disappear. Also, from the same reason in mtypegc we need the rcu lock...

CVE-2026-98899

The Linux kernel contains a vulnerability in the netfilter: ipset component. The issue stems from improper handling of RCU locked areas ; specifically, when bumping the uref counter , the RCU lock does not need to be maintained because the referred hash table cannot disappear. Additionally, it wa...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: don't hold ci-mlock while waiting for a lease break ack When a cifs.ko client caches a read-handle RH lease via deferred close and a conflicting open arrives, ksmbd breaks the lease and waits for the acknowledgment in...

CVE-2026-98897 ksmbd: don't hold ci->m_lock while waiting for a lease break ack

In the Linux kernel, the following vulnerability has been resolved: ksmbd: don't hold ci-mlock while waiting for a lease break ack When a cifs.ko client caches a read-handle RH lease via deferred close and a conflicting open arrives, ksmbd breaks the lease and waits for the acknowledgment in...

CVE-2026-98897

The Linux kernel (ksmbd) contains a concurrency issue where the system holds the ci->m_lock for read while waiting for a lease break acknowledgment in wait_for_break_ack() for up to 35 seconds. This creates a deadlock scenario with cifs.ko clients: when a client closes a deferred handle, it at...
