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 Wireshark

A NULL pointer exception occurs in the Modbus dissector in Wireshark versions 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17, allowing for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerability in Wireshark

The T.38 dissector crash in Wireshark versions 4.2.0 to 4.0.3, and 4.0.0 to 4.0.13 allows for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the unrestricted use of the BPFBTFLOAD function, which could lead to an out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTFs. This flaw allows a local user to crash the system or escalate their privileges...

Astra Linux – Vulnerability in Linux, Linux 5.10

A stack overflow flaw was discovered in the Linux kernel’s TIPC protocol functionality. This flaw occurs when a user sends a packet containing malicious content, where the number of domain member nodes exceeds the allowed limit of 64. This flaw allows a remote user to crash the system or...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A race condition was detected in the Linux kernel’s IP framework for transforming packets XFRM subsystem, where multiple calls to xfrmprobealgs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: scsi: qla2xxx: Fixed a crash that occurred during module load/unload tests. During the purex packet handling, the driver incorrectly freed a pre-allocated structure. This issue was fixed by skipping that specific entry in the...

Astra Linux – Vulnerability in Linux 5.10

A double-free bug in the packetsetring function in net/packet/afpacket.c can be exploited by a local user through crafted syscalls to escalate privileges or deny services. We recommend upgrading the kernel to a version that is not affected by this bug, or rebuilding the code after the...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A vulnerability has been discovered in the Linux kernel. It has been classified as problematic. The affected function is nilfsnew inode in the file fs/nilfs2/inode.c of the BPF component. This vulnerability allows for manipulation after the memory allocation function free is called. The attack ca...

openssl: QUIC server may trigger double free when processing INITIAL packet

A flaw was found in OpenSSL. A malformed INITIAL packet with an invalid DCID destination connection ID can cause the QUIC server to double free the QRX object. This issue leads to memory corruption, causing the termination of the QUIC server process and resulting in a denial of service...

openssl: QUIC ACK-only packet retention can cause memory exhaustion

A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...

openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server

A flaw was found in OpenSSL. A remote attacker could exploit this by sending a large number of QUIC Initial packets to an OpenSSL QUIC server. This can cause the server to allocate and queue new incoming channels without limit, leading to unbounded memory growth. The excessive memory consumption...

CVE-2026-59570: Improper Input Validation

On affected versions of Zscaler client connector, a pre-installed peer app can tear down the Zscaler tunnel, force user logout, and toggle packet capture...

Important: bluez

Issue Overview: A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response EIR packet that causes a buffer overflow when the target device performs Bluetooth...
