In the Linux kernel, the following vulnerability has been resolved: usb: ulpi: fix memory leak on ulpiregister error paths Commit 01af542392b5 "usb: ulpi: fix double free in ulpiregisterinterface error path" removed kfreeulpi from ulpiregisterinterface to fix a double-free when deviceregister...

SUSE CVE-2026-46110

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Prevent NULL deref when RX memory exhausted The CPU receives frames from the MAC through conventional DMA: the CPU allocates buffers for the MAC, then the MAC fills them and returns ownership to the CPU. For each...

SUSE CVE-2026-46112

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix unlocked call to hnsroceqpremove Sashiko points out that hnsroceqpremove requires the caller to hold locks. The error flow in hnsrocecreateqpcommon doesn't hold those locks for the error unwind so it risks corruptin...

SUSE CVE-2026-46114

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Reject non-8-byte ATOMICWRITE payloads atomicwritereply at drivers/infiniband/sw/rxe/rxeresp.c unconditionally dereferences 8 bytes at payloadaddrpkt: value = u64 payloadaddrpkt; checkrkey previously accepted an...

In the Linux kernel, the following vulnerability has been resolved: pseries/papr-hvpipe: Fix null ptr deref in paprhvpipedevcreatehandle commit 6d3789d347a7 "papr-hvpipe: convert paprhvpipedevcreatehandle to FDPREPARE", changed the create handle to FDPREPARE, but it caused kernel null-ptr-deref...

SUSE CVE-2026-46122

In the Linux kernel, the following vulnerability has been resolved: wifi: b43: enforce bounds check on firmware key index in b43rx The firmware-controlled key index in b43rx can exceed the dev-key array size 58 entries. The existing B43WARNON is non-enforcing in production builds, allowing an...

SUSE CVE-2026-46123

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: clamp rx length before skbput virtbtrxwork calls skbputskb, len where len comes directly from virtqueuegetbuf with no validation against the buffer we posted to the device. The RX skb is allocated in...

SUSE CVE-2026-46125

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: remove station if connection prep fails If connection preparation fails for MLO connections, then the interface is completely reset to non-MLD. In this case, we must not keep the station since it's related to the...

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Fix manadestroywqobj cleanup in manaibcreateqprss Sashiko points out there are two bugs here in the error unwind flow, both related to how the WQ table is unwound. First there is a double i-- on the first failure path...

SUSE CVE-2026-46127

In the Linux kernel, the following vulnerability has been resolved: RDMA/ocrdma: Don't NULL deref uctx on errors in ocrdmacopypduresp Sashiko points out that pd-uctx isn't initialized until late in the function so all these error flow references are NULL and will crash. Use the uctx that isn't NU...

SUSE CVE-2026-46130

In the Linux kernel, the following vulnerability has been resolved: dm-verity-fec: fix reading parity bytes split across blocks take 3 fecdecodebufs assumes that the parity bytes of the first RS codeword it decodes are never split across parity blocks. This assumption is false. Consider...
