Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: BPF: Fixed kernel address leakage in atomic cmpxchg operations with R0 as an auxiliary register. The implementation of BPFCMPXCHG at a high level has the following parameters: .-old-val .-new-val BPFR0 = cmpxchg32,64DSTREG +...

Astra Linux – Vulnerability in RustC

In the standard library of Rust before version 1.52.0, there was an optimization for joining strings that could cause uninitialized bytes to be exposed or the program to crash if the borrowed string changed after its length was checked...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Correctly track subprogram poke descriptors and fix use-after-free Subprograms call mappoketrack, but during program release, there is no hook to call mappokeuntrack. However, during program release, the auxiliary memory and...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: virtionet: Fixed an issue with error unwinding of XDP initialization. When initializing XDP in virtnetopen, some rq xdp initializations may encounter errors, resulting in failed network device openings. However, previous rqs have...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Detecting IP == ksym.end as part of the BPF program Now, since bpfthrow is the first call instruction with noreturn semantics within the verifier, this also leads to the elimination of dead code in unprecedented ways. For...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Fixed the re-attachment branch in bpftracingprogattach. The following scenario can cause a crash due to a missing attachbtf: 1 Load the rawtp program. 2 Load the fentry program with rawtp as targetfd. 3 Create a tracing...

Astra Linux – Vulnerability in dcmtk

DCMTK through version 3.6.6 does not handle memory deallocation properly. The object in the program is freed, but its address is still used in other locations. Sending specific requests to the dcmqrdb program will lead to a double-free. An attacker can use this vulnerability to launch a DoS attac...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: mtkethsoc: Reset the progptr to oldprog in case of an error in mtkxdpsetup. Reset the eBPF program pointer to oldprog, and do not decrease its reference count if the mtkopen routine in mtkxdpsetup fails...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in the GNU Binutils through version 2.31. There is a heap-based buffer overflow in the bfdelf32swapphdrin function in elfcode.h, because the number of program headers is not restricted...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Ice: Fixed DMA mapping leaks The leak was fixed when the user changed ring parameters. During the reallocation of RX buffers, new DMA mappings are created for those buffers. New buffers with a different RX ring count should...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed the exclusive map memory leak When exclproghash is 0 and exclproghashsize is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, similar to the memory leak issue reported by syzbo...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an issue in verifying allowptrleaks. After we changed the capabilities of our networking-bpf program from capsysadmin to capnetadmin+capbpf, our networking-bpf program failed to start. This was because it failed the bp...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Ice: Avoid bpfprog refcount underflow The Ice driver includes routines for managing XDP resources that are shared between the ndobpf operation and the VSI rebuild flow. The latter occurs, for example, when the user changes the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fix tailcallreachable rejection for interpreter when jit failed During testing of f263a81451c1 “bpf: Track subprog poke descriptors correctly and fix use-after-free” under various failure conditions, for example, when...

Astra Linux – Vulnerability in NTP

In the file libntp/mstolfp.c, within the NTP 4.2.8p15 version, there is a buffer overflow vulnerability when adding a decimal point. An attacker may be able to exploit a client ntpq process, but they cannot exploit ntpd...

Astra Linux – Vulnerability in glibc

A flaw was discovered in glibc. A “off-by-one” buffer overflow and underflow in the getcwd function may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and the size passed to getcwd in a setuid program could exploit this flaw t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Fixed potential improper dereferencing of pointers 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...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: prevents the LSM program from leaking after a failed attach. In 0, we added the ability to use bpfprogattach for LSM programs within cgroups. However, during our validation to ensure that the program is indeed attached to...
