kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

CVE-2026-18107

A flaw was found in CRIU's handling of restartable sequences rseq during checkpoint/restore. A malicious process inside a container can register an rseq critical section that hijacks CRIU's parasite code injection during checkpoint, allowing it to spoof the process credentials saved in the...

In the Linux kernel, the following vulnerability has been resolved: usbnet: gl620a: fix out-of-bounds read in genelinkrxfixup genelinkrxfixup splits an aggregated RX frame into its individual packets, using a per-packet length taken from device-supplied data. That length is only bounded by...

SUSE CVE-2026-64541

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix UAF in smccdcrxhandler by pinning the socket smccdcrxhandler looks up the connection by token under the link group's connslock, drops the lock, and then dereferences conn and the smcsock derived from it, ending in...

SUSE CVE-2026-64546

In the Linux kernel, the following vulnerability has been resolved: drm/edid: fix OOB read in drmparsetiledblock drmparsetiledblock casts the DisplayID block to a struct displayidtiledblock and reads the full fixed layout up to tile-topologyid7 without checking block-numbytes. The DisplayID...

SUSE CVE-2026-64548

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...

SUSE CVE-2026-64550

In the Linux kernel, the following vulnerability has been resolved: net: qualcomm: rmnet: validate MAP frame length before ingress parsing When ingress deaggregation is disabled, rmnetmapingresshandler passes the skb straight to rmnetmapingresshandler, skipping the length validation that...

SUSE CVE-2026-64552

In the Linux kernel, the following vulnerability has been resolved: virtio-net: fix len check in receivebig receivebig bounds the device-announced length by bigpacketsnumskbfrags + 1 PAGESIZE. That is still too loose: addrecvbufbig sets sg1 to start at offset sizeofstruct paddedvnethdr into the...

SUSE CVE-2026-64553

In the Linux kernel, the following vulnerability has been resolved: net: psample: fix info leak in PSAMPLEATTRDATA psample open codes nlaput presumably to avoid wiping the data with 0s just to override it with packet data. This open coding is missing clearing the pad, however, each netlink attr i...

SUSE CVE-2026-64554

In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: fix stale prevhdr pointer in brip6fragment brip6fragment gets prevhdr, a pointer into the skb head, from ip6find1stfragopt, then calls skbchecksumhelp. For a cloned skb skbchecksumhelp reallocates the head via...

Security update for the Linux Kernel (Live Patch 18 for SUSE Linux Enterprise 15 SP7)

This update for the SUSE Linux Enterprise Kernel 6.4.0-150700.53.66 fixes various security issues: The following security issues were fixed: CVE-2026-53366: ipv4: account for fraggap on the paged allocation path bsc1271370. Patch Instructions: To install this SUSE update use the SUSE recommended...

CVE-2026-64382

A flaw was found in the Linux kernel's Server Message Block SMB client. A double-free vulnerability exists in the SMB2open replay mechanism. This occurs when a response-bearing attempt returns a replayable error and frees its response buffer, and then the cleanup process attempts to free the same...

CVE-2026-64260

A flaw was found in the fuse-uring component of the Linux kernel. A race condition exists where the queue-stopped flag is not consistently checked under a lock. This can allow a struct fusereq to be prematurely freed while other operations are still in progress, potentially leading to memory...

CVE-2026-64265

A flaw was found in the Linux kernel's fuse component. When a fuse request is interrupted and then resent, a specific interrupt entry intrentry is not properly cleared. If the requesting task subsequently receives a fatal signal, this uncleared entry can lead to a use-after-free condition. This...

CVE-2026-64300

A flaw was found in the Linux kernel's perf/aux subsystem. A use-after-free UAF vulnerability exists in the maprange function due to a race condition. This can occur when two performance events share a ring buffer, allowing a local attacker to map a memory page that has already been freed...

CVE-2026-64481

A flaw was found in the Linux kernel's ALSA sound driver for the cs35l41 component. This vulnerability occurs because the driver fails to properly remove controls and cancel firmware load work during component unbinding or device removal, especially when firmware autostart is disabled. This can...

CVE-2026-64281

A flaw was found in the Linux kernel's svcrdma component. During transport teardown, threads waiting in svcrdmasqwait can hang indefinitely in an uninterruptible state. This occurs because these threads are not explicitly woken up when the transport closes, leading to them continuously holding...

CVE-2026-64369

A flaw was found in the Linux kernel, specifically within the s390 architecture. When the system attempts to read unaligned data that spans across memory pages, it can trigger exceptions. For memory pages designated for secure execution by the Ultravisor, the exception handling mechanism does not...

CVE-2026-64278

A flaw was found in the Linux kernel's i2c: imx-lpi2c driver. During system suspend and resume operations, certain I2C client drivers may attempt to perform I2C transfers while the underlying hardware resources are temporarily unavailable. This can occur because the I2C adapter is not properly...

CVE-2026-64448

A flaw was found in the Linux kernel's Server Message Block SMB client. An attacker, by operating a malicious SMB server, could send specially crafted responses during the session negotiation phase. This could cause the client to read beyond the intended memory buffer, potentially leading to the...
