CVE-2025-40299

CVE-2025-40299 concerns the Linux kernel gve code path: ptp_clock_gettime() and ptp_sys_offset() assume a clock implements gettimex64 or gettime64, and a stubbed gettimex64 now returns -EOPNOTSUPP to prevent NULL dereferencing. Connected sources confirm the issue is in gve's gettimex64 handling a...

CVE-2025-40299 gve: Implement gettimex64 with -EOPNOTSUPP

In the Linux kernel, the following vulnerability has been resolved: gve: Implement gettimex64 with -EOPNOTSUPP gve implemented a ptpclock for sole use of doauxwork at this time. ptpclockgettime and ptpsysoffset assume every ptpclock has implemented either gettimex64 or gettime64. Stub gettimex64...

CVE-2025-40298

CVE-2025-40298 concerns the Linux kernel. The root cause is that ptp_clock_settime() assumes every ptp_clock implements settime64(), which could lead to a NULL dereference. The fix implements settime64 in gve and stubs ptp_clock_settime() with -EOPNOTSUPP for clocks that do not support it, preven...

PT-2025-49431

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contained a flaw in the ptp clock settime function where it incorrectly assumed that every precision time protocol ptp clock had implemented the settime64 function. This...

CVE-2023-53758

In the Linux kernel, the following vulnerability has been resolved: spi: atmel-quadspi: Free resources even if runtime resume failed in .remove An early error exit in atmelqspiremove doesn't prevent the device unbind. So this results in an spi controller with an unbound parent and unmapped regist...
