In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix refcount saturation and potential UAF in qrtrportremove In qrtrportremove, the socket reference count is decremented via sockput before the port is removed from the qrtrports XArray and before the RCU grace period...

samba: vfs_worm does not block directory modification

A flaw was found in Samba’s vfsworm module. The module is intended to provide write-once, read-many WORM protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share...

CVE-2026-52910

The CVE concerns the Linux kernel: a reuseport cBPF program could be freed without waiting for an RCU grace period, via sk_reuseport_prog_free() when detaching from the setsockopt path. The underlying issue is that bpf_release_orig_filter() and bpf_prog_free() destruct the cBPF program too early,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Ensure that dma-fences comply with safe access rules. The xe mechanism can free some of the data pointed to by the dma-fences it exports. Notably, the “timeline name” can be freed if the user space closes the associated...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp: Route lookups now perform under a RCU read-side lock. Our current route lookups mctproutelookup and mctproutelookupnull traverse the network’s route list without holding the RCU read lock. This means that the route lookups...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: NFSD: Deferred sub-object cleanup in export put callbacks The svcexportput function calls pathput and authdomainput immediately when the last reference is dropped, before the RCU grace period. RCU readers in eshow and cshow...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: oss: Fixed an issue where PCM OSS buffer allocation might overflow. We have received reports of situations where INTMAX overflow occurs during memory allocation using vmalloc, specifically in the function sndpcmplugalloc...

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: netfilter: nftables – Release flowtable after the rcu grace period with an error. The function synchronizercu is called after unregistering the hooks from the error path. This is because a hook that already references this...

Astra Linux – Vulnerability in golang-github-golang-jwt-jwt

golang-jwt is a Go implementation of JSON Web Tokens. Starting from version 3.2.0 and before versions 5.2.2 and 4.5.2, the parse.ParseUnverified function splits its argument which is untrusted data using periods. As a result, in the case of a malicious request where the Authorization header...

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

In the Linux kernel, the following vulnerabilities have been resolved: netsched: schsfq: rejecting invalid perturb periods. Gerrard Tai reported that the perturbperiod of SFQ does not have a range check yet, and this could be exploited to trigger a race condition, which has been fixed in a separa...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Disabling period-elapsed work when closing PCM The avsdaifeshutdown function handles the shutdown procedure for the HOST HAudio stream. Period-elapsed work processes its IRQs. Since the former frees the DAI’s...

kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...
