CVE-2026-52998
In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkosf: fix potential NULL dereference in ttl check The nfosfttl function accessed skb-dev to perform a local interface address lookup without verifying that the device pointer was valid. Additionally, the...
CVE-2026-52998
CVE-2026-52998 affects the Linux kernel’s netfilter nfnetlink_osf module. The nf_osf_ttl() function can dereference a device pointer (skb->dev) without validating the device, risking a NULL dereference. The patch removes the device dereference and the in_dev_for_each_ifa_rcu loop used to match...
CVE-2026-52957
In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential null-ptr-deref in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. When decoding this CRUSH map in crushdecode, an array of maxbuckets CRUSH buckets is...
CVE-2026-52957
Consolidated details from CVE-2026-52957 show a Linux kernel libceph flaw in processing CEPH_MSG_OSD_MAP: during CRUSH map decoding, bucket indices may reference NULL buckets when decoding crush_choose_arg_map, risking a NULL pointer dereference. A patch extends the validation to only access non-...
CVE-2026-52957 libceph: Fix potential null-ptr-deref in decode_choose_args()
In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential null-ptr-deref in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. When decoding this CRUSH map in crushdecode, an array of maxbuckets CRUSH buckets is...
CVE-2026-52941
A flaw was found in the Linux kernel's net/smc module. An unprivileged local user could trigger a null pointer dereference by performing sendmsg or recvmsg operations on an SMC-D Shared Memory Communications - Direct socket while the smcmsgevent tracepoint is enabled. This can lead to a general...
CVE-2026-52938
A flaw was found in the Linux kernel's Berkeley Packet Filter BPF storage. A race condition can occur where a storage element is accessed after its associated map has been deallocated, leading to a null pointer dereference. This can cause a kernel crash, resulting in a Denial of Service DoS for t...
CVE-2026-52922
A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...
CVE-2026-52939
A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. An unprivileged local user can trigger a kernel panic by sending a specially crafted atomic control message cmsg over an active RDS/InfiniBand IB connection. This issue is caused by improper handling of masked atomic...
CVE-2026-52938
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL pointer dereference in bpfskstorageclone and diag paths bpfselemunlinknofail sets SDATAselem-smap to NULL before removing the selem from the storage hlist. A concurrent RCU reader in bpfskstorageclone can observe th...
CVE-2026-52929
In the Linux kernel, the following vulnerability has been resolved: sctp: stream: fully roll back denied add-stream state When ADDOUTSTREAMS is denied, SCTP only shrinks the queued chunks and then lowers outcnt. That leaves removed stream metadata behind, so a later re-add can reuse a stale ext a...
CVE-2026-52922
In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: handle forward allocation error batadvdatforwarddata calls pskbcopyforclone to duplicate an skb for each DHT candidate, but does not check the return value before passing it to batadvsendskbprepareunicast4addr...
UBUNTU-CVE-2026-52925
In the Linux kernel, the following vulnerability has been resolved: vrf: Fix a potential NPD when removing a port from a VRF RCU readers that identified a net device as a VRF port using netifisl3slave assume that a subsequent call to netdevmasterupperdevgetrcu will return a VRF device. They then...
UBUNTU-CVE-2026-52939
In the Linux kernel, the following vulnerability has been resolved: net/rds: fix NULL deref in rdsibsendcqehandler on masked atomic completion rdsibxmitatomic always programs a masked atomic opcode IBWRMASKEDATOMICCMPANDSWP or IBWRMASKEDATOMICFETCHANDADD for every RDS atomic cmsg. But the...

UBUNTU-CVE-2026-52913
In the Linux kernel, the following vulnerability has been resolved: batman-adv: v: stop OGMv2 on disabled interface When a batadvhardiface is disabled, its meshiface pointer is set to NULL. However, batadvvogmsendmeshif may still dispatch OGMs via batadvvogmqueueonif for interfaces that have sinc...
UBUNTU-CVE-2026-52941
In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid NULL deref of conn-lnk in smcmsgevent tracepoint The smcmsgevent tracepoint class, shared by smctxsendmsg and smcrxrecvmsg, unconditionally dereferences smc-conn.lnk: stringname, smc-conn.lnk-ibname conn-lnk is onl...
CVE-2026-52941
The CVE-2026-52941 issue affects the Linux kernel’s SMC tracepoints. The smc_msg_event tracepoint unconditionally dereferences smc->conn.lnk->ibname, causing a NULL dereference when conn->lnk is NULL on SMC-D (while it is set for SMC-R). This can crash the first sendmsg()/recvmsg() on an...
