The vulnerability of the ksz_setup() function in the drivers/net/dsa/microchip/ksz_common.c file of the DSA kernel of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the kszsetup function in the drivers/net/dsa/microchip/kszcommon.c file of the DSA kernel of the Linux operating system is related to the access to an uninitialized pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Networking layer: dsa: Microchip: Do not free uninitialized kszirq. If there are issues during initialization, the kszirqfree function may be called on uninitialized kszirq values for example, when kszptpirqsetup fails. This can...

CVE-2026-12619

Improper Neutralization of Input During Web Page Generation XSS or 'Cross-site Scripting' vulnerability in Microchip GridTime 3000 allows Cross-Site Scripting XSS. This issue affects GridTime 3000: from 1.0r0.03 through 1.1r0.0...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clk: microchip: mpfs-ccc: fixed an out-of-bounds access during output registration. UBSAN reported an out-of-bounds access during the registration of the last two outputs. This out-of-bounds access occurs because space is only...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: spi: microchip-core-qspi: Do not attempt to transmit during emulated read-only dual/quad operations. The core will handle reads by generating clock cycles itself; there is no need to generate clock cycles by transmitting garbage...
