In the Linux kernel, the following vulnerability has been resolved: ext4: avoid online resizing failures due to oversized flex bg When we online resize an ext4 filesystem with a oversized flexbg_size, mkfs.ext4 -F -G 67108864 $dev -b 4096 100M mount $dev $dir resize2fs $dev 16G the following WARN_ON is triggered: ================================================================== WARNING: CPU: 0 PID: 427 at mm/page_alloc.c:4402 __alloc_pages+0x411/0x550 Modules linked in: sg(E) CPU: 0 PID: 427 Comm: resize2fs Tainted: G E 6.6.0-rc5+ #314 RIP: 0010:__alloc_pages+0x411/0x550 Call Trace: <TASK> __kmalloc_large_node+0xa2/0x200 __kmalloc+0x16e/0x290 ext4_resize_fs+0x481/0xd80 __ext4_ioctl+0x1616/0x1d90 ext4_ioctl+0x12/0x20 __x64_sys_ioctl+0xf0/0x150 do_syscall_64+0x3b/0x90 ================================================================== This is because flexbg_size is too large and the size of the new_group_data array to be allocated exceeds MAX_ORDER. Currently, the minimum value of MAX_ORDER is 8, the minimum value of PAGE_SIZE is 4096, the corresponding maximum number of groups that can be allocated is: (PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845 And the value that is down-aligned to the power of 2 is 16384. Therefore, this value is defined as MAX_RESIZE_BG, and the number of groups added each time does not exceed this value during resizing, and is added multiple times to complete the online resizing. The difference is that the metadata in a flex_bg may be more dispersed. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ext4: evita fallos de cambio de tamaño en línea debido a flex bg sobredimensionado Cuando redimensionamos en línea un sistema de archivos ext4 con un flexbg_size sobredimensionado, mkfs.ext4 -F -G 67108864 $dev -b 4096 100M mount $dev $dir resize2fs $dev 16G se activa el siguiente WARN_ON: ===================================== ============================== ADVERTENCIA: CPU: 0 PID: 427 en mm/page_alloc.c:4402 __alloc_pages+0x411/ 0x550 Módulos vinculados en: sg(E) CPU: 0 PID: 427 Comm: resize2fs Contaminado: GE 6.6.0-rc5+ #314 RIP: 0010:__alloc_pages+0x411/0x550 Seguimiento de llamadas: __kmalloc_large_node+0xa2/0x200 __kmalloc+ 0x16e/0x290 text4_resize_fs+0x481/0xd80 __ext4_ioctl+0x1616/0x1d90 text4_ioctl+0x12/0x20 __x64_sys_ioctl+0xf0/0x150 do_syscall_64+0x3b/0x90 ======== =============== ============================================ Esto se debe a que flexbg_size también lo es grande y el tamaño de la matriz new_group_data que se asignará excede MAX_ORDER. • https://git.kernel.org/stable/c/cd1f93ca97a9136989f3bd2bf90696732a2ed644 https://git.kernel.org/stable/c/b183fe8702e78bba3dcef8e7193cab6898abee07 https://git.kernel.org/stable/c/cfbbb3199e71b63fc26cee0ebff327c47128a1e8 https://git.kernel.org/stable/c/d76c8d7ffe163c6bf2f1ef680b0539c2b3902b90 https://git.kernel.org/stable/c/6d2cbf517dcabc093159cf138ad5712c9c7fa954 https://git.kernel.org/stable/c/8b1413dbfe49646eda2c00c0f1144ee9d3368e0c https://git.kernel.org/stable/c/dc3e0f55bec4410f3d74352c4a7c79f518088ee2 https://git.kernel.org/stable/c/5d1935ac02ca5aee364a449a35e2977ea • CWE-131: Incorrect Calculation of Buffer Size •

In the Linux kernel, the following vulnerability has been resolved: NFC: nci: fix memory leak in nci_allocate_device nfcmrvl_disconnect fails to free the hci_dev field in struct nci_dev. Fix this by freeing hci_dev in nci_free_device.
