grub2: commands/extcmd: Missing check for failed allocation

A flaw was found in grub2 where the grubextcmddispatcher function calls grubarglistalloc to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parseoption function, leading...

xorg: xwayland: Use of uninitialized pointer in compRedirectWindow()

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow will return a BadAlloc error without validating the window tree marked just before, which leaves the...

kernel: static_call: Replace pointless WARN_ON() in static_call_module_notify()

In the Linux kernel, the following vulnerability has been resolved: staticcall: Replace pointless WARNON in staticcallmodulenotify staticcallmodulenotify triggers a WARNON, when memory allocation fails in staticcalladdmodule. That's not really justified, because the failure case must be correctly...

kernel: x86/ioapic: Handle allocation failures gracefully

A flaw was found in the Linux kernel's x86 IO-APIC Input/Output Advanced Programmable Interrupt Controller component. A local attacker with low privileges could trigger an interrupt allocation failure under specific runtime conditions. This failure would lead to a kernel panic, resulting in a...

kernel: scsi: target: core: Fix null-ptr-deref in target_alloc_device()

A flaw was found in the Linux kernel's SCSI target core. When memory allocation for device queues fails within the targetallocdevice function, the system attempts to free an uninitialized device transport structure. This can lead to a null pointer dereference, allowing a local attacker with low...

kernel: brd: defer automatic disk creation until module initialization succeeds

In the Linux kernel, the following vulnerability has been resolved: brd: defer automatic disk creation until module initialization succeeds My colleague Wupeng found the following problems during fault injection: BUG: unable to handle page fault for address: fffffbfff809d073 PGD 6e648067 P4D...

CVE-2023-53139

The CVE-2023-53139 issue is in the Linux kernel’s NFC FDP code: it adds a null check for devm_kmalloc_array in fdp_nci_i2c_read_device_properties. If devm_kmalloc_array fails and fw_vsc_cfg is NULL, an out-of-bounds write can occur in device_property_read_u8_array. The vulnerability is addressed ...
