CVE-2022-49962

CVE-2022-49962 affects the Linux kernel xHCI driver: the remove path could dereference a null pointer when xHC has only one roothub, attempting to remove both main and shared hcds even if the shared_hcd doesn’t exist. This could trigger a NULL pointer dereference during reboot for affected contro...

In the Linux kernel, the following vulnerability has been resolved: bpf: Do markchainprecision for ARGCONSTALLOCSIZEORZERO Precision markers need to be propagated whenever we have an ARGCONST style argument, as the verifier cannot consider imprecise scalars to be equivalent for the purposes of...

CVE-2022-49957 kcm: fix strp_init() order and cleanup

In the Linux kernel, the following vulnerability has been resolved: kcm: fix strpinit order and cleanup strpinit is called just a few lines above this csk-skuserdata check, it also initializes strp-work etc., therefore, it is unnecessary to call strpdone to cancel the freshly initialized work. An...

CVE-2022-49957

CVE-2022-49957 concerns a Linux kernel issue in the kcm path where strp_init() is invoked before the csk->sk_user_data check. The vulnerability arises because strp_init() initializes strp->work (and others); calling strp_done() to cancel it is unnecessary if sk_user_data isn’t checked yet. ...

CVE-2022-49955

Summary of CVE-2022-49955 : This vulnerability concerns the Linux kernel’s powerpc/rtas code, where MSR[HV] handling for IBM Cell during RTAS entry could crash the system. The root cause, as described across sources, is a mismatch in how MSR[HV] is treated when RTAS is invoked (firmware/RTAS inte...

CVE-2022-49954

The CVE-2022-49954 issue concerns the Linux kernel and a race where, after clearing IFORCE_XMIT_RUNNING, wake_up was not invoked, causing a hung task in input handling (hang at __input_unregister_device() during iforce_close and input_disconnect_device()). The root cause per the provided descript...

CVE-2022-49953

CVE-2022-49953 concerns the Linux kernel’s iio: light cm3605 driver. The issue is an error-handling path in cm3605_probe() that, after a fix, introduced a new error-path which should jump to the existing error-handling path to avoid resource leaks. The connected sources consistently describe this...

CVE-2022-49953 iio: light: cm3605: Fix an error handling path in cm3605_probe()

In the Linux kernel, the following vulnerability has been resolved: iio: light: cm3605: Fix an error handling path in cm3605probe The commit in Fixes also introduced a new error handling path which should goto the existing error handling path. Otherwise some resources leak...

CVE-2022-49952 misc: fastrpc: fix memory corruption on probe

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix memory corruption on probe Add the missing sanity check on the probed-session count to avoid corrupting memory beyond the fixed-size slab-allocated session array when there are more than FASTRPCMAXSESSIONS...

CVE-2022-49948

CVE-2022-49948 affects the Linux kernel VT subsystem. When changing the console font via ioctl(KDFONTOP), the new font size may exceed the previous screen, potentially making a prior selection fall outside the new viewport and cause out-of-bounds accesses to graphics memory if the selection is re...

CVE-2022-49948 vt: Clear selection before changing the font

In the Linux kernel, the following vulnerability has been resolved: vt: Clear selection before changing the font When changing the console font with ioctlKDFONTOP the new font size can be bigger than the previous font. A previous selection may thus now be outside of the new screen size and thus...

In the Linux kernel, the following vulnerability has been resolved: clk: bcm: rpi: Prevent out-of-bounds access The while loop in raspberrypidiscoverclocks relies on the assumption that the id of the last clock element is zero. Because this data comes from the Videocore firmware and it doesn't...

CVE-2022-49945

The CVE-2022-49945 issue affects the Linux kernel hwmon gpio-fan driver. The vulnerability occurs because gpio_fan_set_cur_state() does not validate the cooling state against fan_data->num_speeds, allowing an out-of-bounds index in set_fan_speed(). Practical impact is potential kernel oops or ...
