In the Linux kernel, the following vulnerability has been resolved: dmarraycursorend: Fix to prevent releasing a faulty array block twice when using dmarraycursorend. When dmbmreadlock fails due to locking or checksum errors, it releases the faulty block implicitly, leaving an invalid output...

Astra Linux – Vulnerability in OpenSSL

The function PEMreadbioex reads a PEM file from a BIO, parses, and decodes the “name” e.g., “CERTIFICATE”, any header data, and the payload data. If the function succeeds, the “nameout”, “header”, and “data” arguments are populated with pointers to buffers containing the relevant decoded data. Th...

In the Linux kernel, the following vulnerabilities have been resolved: nfs: fixed UAF in direct writes In production, we have been encountering the following warnings consistently: ------------ cut here ------------ refcountt: underflow; use-after-free. WARNING: CPU: 17 PID: 1800359 at...

Astra Linux – Vulnerability in Linux, Linux 5.10

A memory leak flaw in the Linux kernel’s hugetlbfs memory usage was discovered in the way that the system maps some regions of memory twice using shmget. These mappings are aligned according to PUD alignment, resulting in some memory pages being misaligned. A local user could exploit this flaw to...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfsd: calls oprelease, even when opfunc returns an error. For operations with “trivial” responses, nfsd4encodeoperation will shortcut most of the encoding process and simply proceed to marshaling the status. One of the things it...

In the Linux kernel, the following vulnerability has been resolved: Tracing: Fixed a potential double-free issue in createvarref. In createvarref, initvarref is called to initialize the fields of the reffield variable. This variable is allocated in the previous function call, to createhistfield...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: A double-free operation in siparsepowertable has been fixed. In the function siparsepowertable, the array adev-pm.dpm.ps and its members are allocated. If the allocation of each member fails, the array itself is freed...

Astra Linux – Vulnerabilities in Firefox, LibWebP, Thunderbird

There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode function and loop through to free the best.bw file, assigning the best pointer to trial. The second loop will then return 0 due to a memory out-of-memory error in the VP8 encoder; the pointer remai...

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fixed the potential double-free of the bit17 bitmask. A userspace environment where multiple threads compete to set the tiling to I915TILINGNONE could lead to a double-free of the bit17 bitmask. Or, conversely, memory...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: IB/mlx5: Fixed error handling during the init stage to avoid double-freeing of the same QP and UAF. In the unlikely event that workqueue allocation fails and returns NULL in mlx5mkeycacheinit, delete the call to...
