https://notcve.org/view.php?id=CVE-2022-49075
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix qgroup reserve overflow the qgroup limit We use extent_changeset->bytes_changed in qgroup_reserve_data() to record how many bytes we set for EXTENT_QGROUP_RESERVED state. Currently the bytes_changed is set as "unsigned int", and it will overflow if we try to fallocate a range larger than 4GiB. The result is we reserve less bytes and eventually break the qgroup limit. Unlike regular buffered/direct write, which we use one changese... • https://git.kernel.org/stable/c/0355387ea5b02d353c9415613fab908fac5c52a6 •

CVE-2022-49072 – gpio: Restrict usage of GPIO chip irq members before initialization
https://notcve.org/view.php?id=CVE-2022-49072
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: gpio: Restrict usage of GPIO chip irq members before initialization GPIO chip irq members are exposed before they could be completely initialized and this leads to race conditions. One such issue was observed for the gc->irq.domain variable which was accessed through the I2C interface in gpiochip_to_irq() before it could be initialized by gpiochip_add_irqchip(). This resulted in Kernel NULL pointer dereference. Following are the logs for re... • https://git.kernel.org/stable/c/7e88a50704b0c49ad3f2d11e8b963341cf68a89f • CWE-476: NULL Pointer Dereference •

CVE-2022-49067 – powerpc: Fix virt_addr_valid() for 64-bit Book3E & 32-bit
https://notcve.org/view.php?id=CVE-2022-49067
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc: Fix virt_addr_valid() for 64-bit Book3E & 32-bit mpe: On 64-bit Book3E vmalloc space starts at 0x8000000000000000. Because of the way __pa() works we have: __pa(0x8000000000000000) == 0, and therefore virt_to_pfn(0x8000000000000000) == 0, and therefore virt_addr_valid(0x8000000000000000) == true Which is wrong, virt_addr_valid() should be false for vmalloc space. In fact all vmalloc addresses that alias with a valid PFN will return... • https://git.kernel.org/stable/c/deab81144d5a043f42804207fb76cfbd8a806978 •
