Vulnerability identifier: #VU93308

CSH Severity: Low

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2024-35909

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to memory corruption within the t7xx_pcie_mac_atr_tables_dis() and t7xx_pcie_mac_atr_cfg() functions in drivers/net/wwan/t7xx/t7xx_pcie_mac.c, within the t7xx_cldma_gpd_rx_from_q() and t7xx_cldma_txq_empty_hndl() functions in drivers/net/wwan/t7xx/t7xx_hif_cldma.c, within the t7xx_cldma_tx_addr_is_set() and t7xx_cldma_hw_set_start_addr() functions in drivers/net/wwan/t7xx/t7xx_cldma.c. A local user can escalate privileges on the system.
