CVE-2026-33278 Possible arbitrary code execution during DNSSEC validation

NLnet Labs Unbound 1.19.1 up to and including version 1.25.0 has a vulnerability in the DNSSEC validator that enables denial of service and possible remote code execution as a result of deep copying a data structure and erroneously overwriting a destination pointer. An adversary can exploit the...

CVE-2026-33278

NLnet Labs Unbound 1.19.1–1.25.0 contains a vulnerability in the DNSSEC validator: during NSEC3-budget–driven validation suspensions, Unbound deep-copies response messages and a struct-assignment overwrites the destination pointer with the source pointer. After freeing the sub-query region, the v...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: PID: Taking a reference when initializing cadpid During boot, kernelinitfreeable initializes cadpid to the struct pid of the init task. Later, we may change cadpid via sysctl. When this happens, procdocadpid will increment the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: No support for struct arguments in trampoline programs The current implementation does not support struct arguments. This causes an oops when running the bpf selftest: $ ./testprogs -a tracingstruct Oops1: CPU -1...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: s390: fixed the issue where double-free of GS and RI CBs occurs during fork failures. The pointers for guarded storage and runtime instrumentation control blocks are stored in the threadstruct of the associated task. These...

Astra Linux – Vulnerability in binutils

A flaw was discovered in Binutils. The use of an uninitialized field in the struct module module may cause the application to crash and lead to a local denial of service...

CVE-2026-43472

The CVE describes a Linux kernel unshare(2) bug: when CLONE_NEWNS is requested and current->fs wasn’t previously shared, copy_mnt_ns() could receive a non-private fs_struct. If copy_mnt_ns() succeeds but a subsequent copy_cgroup_ns() fails, the destroyed namespace can leave current->fs->...

SUSE CVE-2026-43115

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...

EUVD-2026-27574

In the Linux kernel, the following vulnerability has been resolved: net: txgbe: leave space for null terminators on propertyentry Lists of struct propertyentry are supposed to be terminated with an empty property, this driver currently seems to be allocating exactly the amount of entry used. Chan...

CVE-2026-43115 srcu: Use irq_work to start GP in tiny SRCU

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...

CVE-2026-43115

The CVE-2026-43115 entry documents a Linux kernel fix for Tiny SRCU: srcu_gp_start_if_needed() previously called schedule_work(), acquiring pool->lock and triggering a lockdep splat when call_srcu() runs with a scheduler lock held. The remediation adds irq_work_sync() to cleanup_srcu_struct() ...

Potential out-of-bounds write via public `Context` fields

The Context struct has all fields public pub dlen, pub digest, etc.. Code from other modules within the same crate can directly modify dlen to a value exceeding the digest vector length. When reset is subsequently called, self.digestself.dlen as usize = 0 becomes an out-of-bounds write. Withdrawa...
