CVE-2011-1759: Integer overflow in the sys_oabi_semtimedop function in arch/arm/kernel/sys_oabi-compat.c in the Linux kern...

Security readout for executives and security teams

CVE-2011-1759 is a Linux kernel flaw affecting ARM systems before 2.6.39 when OABI compatibility is enabled. A local user could corrupt kernel heap memory, potentially gaining privileges or crashing the system. The supplied sources do not show remote exploitation or active exploitation. Exposure is limited to Linux on ARM, kernel versions before 2.6.39 or unpatched vendor backports, with CONFIG_OABI_COMPAT enabled. Systems without local user access or without OABI compatibility are less likely to be affected based on the provided evidence. Treat as high priority where legacy ARM Linux systems allow local users or untrusted code. For modern kernels or non-ARM estates, urgency is lower but still requires inventory confirmation. Mitigation focus: Upgrade to Linux kernel 2.6.39 or a vendor-fixed backport.; Confirm vendor advisories for affected embedded or appliance distributions.; Disable unnecessary OABI compatibility if vendor guidance supports it..
