EUVD-2026-67478

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/lbr: Fix kernel address leakage A user-only branch stack can contain branches that originate from the kernel. As a result, kernel addresses are exposed to user space even when PERFSAMPLEBRANCHUSER is requested. On AM...

CVE-2026-80602

CVE-2026-80602 is an information disclosure vulnerability in the Linux kernel 's perf/x86/amd/lbr subsystem. On AMD processors supporting X86_FEATURE_AMD_LBR_V2 , the hardware branch filter only validates the privilege level of the branch target , not the branch from address. As a result, SYSRET/...

In the Linux kernel, the following vulnerability has been resolved: Input: cs40l50-vibra - validate custom data from user space cs40l50add copies the custom data of an FFPERIODIC/FFCUSTOM effect straight from the ffeffect the user passed to EVIOCSFF, without requiring it to hold anything:...

CVE-2026-80575 Input: cs40l50-vibra - validate custom data from user space

In the Linux kernel, the following vulnerability has been resolved: Input: cs40l50-vibra - validate custom data from user space cs40l50add copies the custom data of an FFPERIODIC/FFCUSTOM effect straight from the ffeffect the user passed to EVIOCSFF, without requiring it to hold anything:...

CVE-2026-80575

CVE-2026-80575 affects the cs40l50-vibra Linux kernel input driver (a haptic vibration controller). The function cs40l50_add() copies user-supplied custom_data from an FF_PERIODIC/FF_CUSTOM effect via the EVIOCSFF ioctl without sufficient validation. Three distinct issues exist: custom_len == 0 c...

PT-2026-82191

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the cs40l50 add function where custom data from an FF PERIODIC or FF CUSTOM effect is copied from user space via EVIOCSFF without sufficient validation of the custom l...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algorithms and encap templates. When copying data to user-space, we must ensure that only valid data is copied. Padding in structures may contain random potentially sensitive data and should never ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86/pmu: Disabled support for adaptive PEBS. Support for virtualizing adaptive PEBS has been discontinued. This is because KVM’s implementation is architecturally broken without an obvious or easy way to address the issue...

Astra Linux – Vulnerability in Linux, Linux 5.10

There is a bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by simulating an NFC device from user-space...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fixed the issue where immediate work requests were flushed to the completion queue prematurely. The opcode of the send queue element was correctly set during the flushing of immediate work requests in the post-sendqueue...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: perf: Improved missing SIGTRAP checks To detect missing SIGTRAP checks, we use a WARN in perfeventoverflow. This warning is triggered if pendingsigtrap was already set—meaning the process returns to user space without consuming...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tee: added a overflow check in registershmhelper When special lengths are provided by the user space, registershmhelper may cause an integer overflow when calculating the number of pages covered by a given user space memory regio...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free vulnerability...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Fixed potential improper pointer dereferencing in bpfsysbpf. The bpfsysbpf helper function allows an eBPF program to load another eBPF program from within the kernel. In this case, the argument union bpfattr pointer along...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Properly handles malformed BPFCORETYPEIDLOCAL relocation records. In the case of malformed relocation records of the BPFCORETYPEIDLOCAL type that reference a non-existent BTF type, the function bpfcorecalcreloinsn may cause ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rcv: process: Fix kernel gp leakage childregs represents the registers that are active for the new thread in the user context. For a kernel thread, childregs-gp is never used, as the kernel’s gp value is not touched by the switch...

CVE-2026-74707

In the Linux kernel, the following vulnerability has been resolved: xsk: validate metadata when processing requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it again later when preparing the hardware request. User space can change the metadata...

CVE-2026-74709

CVE-2026-74709 affects the AF_XDP (xsk) subsystem in the Linux kernel. The root cause is that user space can modify metadata flags after a TX request has been processed; when the kernel rereads those flags during completion, it may write a timestamp into the metadata area that was never requested...

CVE-2026-74709 xsk: clear metadata pointer when no timestamp is requested

In the Linux kernel, the following vulnerability has been resolved: xsk: clear metadata pointer when no timestamp is requested User space can change metadata flags after request processing. Rereading them during completion can therefore make the kernel write a timestamp that was not requested whe...
