DEBIAN-CVE-2025-22108

In the Linux kernel, the following vulnerability has been resolved: bnxten: Mask the bdcnt field in the TX BD properly The bdcnt field in the TX BD specifies the total number of BDs for the TX packet. The bdcnt field has 5 bits and the maximum number supported is 32 with the value 0...

DEBIAN-CVE-2025-22095

In the Linux kernel, the following vulnerability has been resolved: PCI: brcmstb: Fix error path after a call to regulatorbulkget If the regulatorbulkget returns an error and no regulators are created, we need to set their number to zero. If we don't do this and the PCIe link up fails, a call to...

UBUNTU-CVE-2025-22074

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix rcount dec/increment mismatch rcount is only increased when there is an oplock break wait, so rcount inc/decrement are not paired. This can cause rcount to become negative, which can lead to a problem where the ksmbd...

DEBIAN-CVE-2025-22040

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix session use-after-free in multichannel connection There is a race condition between session setup and ksmbdsessionsderegister. The session can be freed before the connection is added to channel list of session. This...

CVE-2025-22083

The CVE-2025-22083 issue affects Linux kernel vhost-scsi handling: multiple vhost_scsi_set_endpoint calls without an intervening vhost_scsi_clear_endpoint can trigger three bugs in the vs_tpg lifecycle. 1) Use-after-free when no tpgs are found after a second call, due to freed vs->vs_tpg backi...

CVE-2025-22077

CVE-2025-22077 concerns Linux kernel CIFS SMB client TCP timers deadlock after rmmod. The advisory notes the patch that attempted to fix a NULL dereference in LOCKDEP via a CIFS netns reference was reverted, reviving a kernel TCP socket timer lifecycle mismatch. This reversion can cause FIN_WAIT_...

CVE-2025-22072

CVE-2025-22072 affects the Linux kernel spufs component, addressing leaks in gang directory lifetimes. The issue: creating a gang returns an opened gang directory that should be removed on close, but if a context belonging to that gang remains alive, removal could fail, causing a leak. The fix de...

CVE-2025-22025

CVE-2025-22025: In the Linux kernel NFS server (nfsd), if nfsd4_run_cb fails while queuing a dl_recall, the incremented dl_stid reference is not decremented, causing a potential dl_stid leak. The issue is addressed by checking the result of nfsd4_run_cb and, on failure, calling nfs4_put_stid to p...
