CVE-2026-93246

A vulnerability in the Linux kernel (specifically the octeontx2-af driver) allows an out-of-bounds read during the setting of MSI-X IRQ affinity. The rvu_register_interrupts() function uses strstr() to search for "Mbox" or "FLR" within the irq_name buffer. Because this buffer may contain uninitia...

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix out-of-bounds read setting MSI-X irq affinity rvuregisterinterrupts walks every MSI-X vector and uses strstr to match "Mbox" or "FLR" in irqname before pinning those interrupts to CPU 0. irqname is a per-vector...

The vulnerabilities of the functions cgx_lmac_write() and cgx_lmac_read() in the driver file drivers/net/ethernet/marvell/octeontx2/af/cgx.c of the Linux operating system’s network controller driver for Marvell OcteonTX2 AF cores allow a hacker to cause service failures.

The vulnerabilities of the functions cgxlmacwrite and cgxlmacread in the file drivers/net/ethernet/marvell/octeontx2/af/cgx.c of the network controller driver for the Marvell OcteonTX2 AF in the Linux operating system are related to insufficient resource management during its existence. Exploitin...
