Security update for the Linux Kernel

The SUSE Linux Enterprise 12 SP5 Azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2022-38096: Fixed NULL-ptr deref in vmw_cmd_dx_define_query() (bsc#1203331). - CVE-2022-4129: Fixed a denial of service with the Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. (bsc#1205711) - CVE-2023-0597: Fixed lack of randomization of per-cpu entry area in x86/mm (bsc#1207845). - CVE-2023-1118: Fixed a use-after-free bugs caused by ene_tx_irqsim() in media/rc (bsc#1208837). - CVE-2023-23559: Fixed integer overflow in rndis_wlan that leads to a buffer overflow (bsc#1207051). - CVE-2023-26545: Fixed double free in net/mpls/af_mpls.c upon an allocation failure (bsc#1208700). The following non-security bugs were fixed: - bonding: fix 802.3ad state sent to partner when unbinding slave (git-fixes). - do not sign the vanilla kernel (bsc#1209008). - icmp: do not fail on fragment reassembly time exceeded (git-fixes). - ipmi: fix initialization when workqueue allocation fails (git-fixes). - ipmi: msghandler: Make symbol 'remove_work_wq' static (git-fixes). - kabi fix for - SUNRPC: Fix priority queue fairness (git-fixes). - kabi fix for: NFS: Pass error information to the pgio error cleanup routine (git-fixes). - kabi/severities: add l2tp local symbols - kernel-module-subpackage: Fix expansion with -b parameter (bsc#1208179). When -b is specified the script is prefixed with KMP_NEEDS_MKINITRD=1 which sets the variable for a simple command. However, the script is no longer a simple command. Export the variable instead. - media: coda: Add check for dcoda_iram_alloc (git-fixes). - media: coda: Add check for kmalloc (git-fixes). - media: platform: ti: Add missing check for devm_regulator_get (git-fixes). - net: aquantia: fix RSS table and key sizes (git-fixes). - netfilter: ipvs: Fix inappropriate output of procfs (git-fixes). - netfilter: xt_connlimit: do not store address in the conn nodes (git-fixes). - nfs: Fix nfsi->nrequests count error on nfs_inode_remove_request (git-fixes). - nfs: Pass error information to the pgio error cleanup routine (git-fixes). - nfsd: fix handling of readdir in v4root vs. mount upcall timeout (git-fixes). - nfsd: fix race to check ls_layouts (git-fixes). - nfsd: under NFSv4.1, fix double svc_xprt_put on rpc_create failure (git-fixes). - ocfs2: Fix data corruption after failed write (bsc#1208542). - pNFS/filelayout: Fix coalescing test for single DS (git-fixes). - powerpc/eeh: Fix use-after-release of EEH driver (bsc#1065729). - powerpc/fscr: Enable interrupts earlier before calling get_user() (bsc#1065729). - powerpc/powernv: Fix build error in opal-imc.c when NUMA=n (bsc#1065729). - powerpc/powernv: IMC fix out of bounds memory access at shutdown (bsc#1065729). - scsi: qla2xxx: Add option to disable FC2 Target support (bsc#1198438 bsc#1206103). - sunrpc: Fix priority queue fairness (git-fixes). - sunrpc: ensure the matching upcall is in-flight upon downcall (git-fixes). - vlan: Fix out of order vlan headers with reorder header off (git-fixes). - vlan: Fix vlan insertion for packets without ethernet header (git-fixes). - vxlan: Fix error path in __vxlan_dev_create() (git-fixes). - vxlan: changelink: Fix handling of default remotes (git-fixes). - xfrm: Copy policy family in clone_policy (git-fixes).
