GHSA-7278-8HVX-PP94
Vulnerability from github – Published: 2023-07-01 00:30 – Updated: 2025-11-03 21:30A null pointer dereference issue was discovered in Libtiff's tif_dir.c file. This flaw allows an attacker to pass a crafted TIFF image file to the tiffcp utility, which triggers runtime error, causing an undefined behavior, resulting in an application crash, eventually leading to a denial of service.

In the event of a skipped partition (case when the entry name is empty) the kernel panics in the cleanup function as the name entry is NULL. Rework the parser logic by first checking the real partition number and then allocate the space and set the data for the valid partitions.
The logic was also fundamentally wrong as with a skipped partition, the parts number returned was incorrect by not decreasing it for the skipped partitions.

GHSA-737F-4C7F-CGC8
Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-17 18:30In the Linux kernel, the following vulnerability has been resolved:
BPF: Fix potential bad pointer dereference in bpf_sys_bpf()
The bpf_sys_bpf() helper function allows an eBPF program to load another eBPF program from within the kernel. In this case the argument union bpf_attr pointer (as well as the insns and license pointers inside) is a kernel address instead of a userspace address (which is the case of a usual bpf() syscall). To make the memory copying process in the syscall work in both cases, bpfptr_t was introduced to wrap around the pointer and distinguish its origin. Specifically, when copying memory contents from a bpfptr_t, a copy_from_user() is performed in case of a userspace address and a memcpy() is performed for a kernel address.
This can lead to problems because the in-kernel pointer is never checked for validity. The problem happens when an eBPF syscall program tries to call bpf_sys_bpf() to load a program but provides a bad insns pointer -- say 0xdeadbeef -- in the bpf_attr union. The helper calls __sys_bpf() which would then call bpf_prog_load() to load the program. bpf_prog_load() is responsible for copying the eBPF instructions to the newly allocated memory for the program; it creates a kernel bpfptr_t for insns and invokes copy_from_bpfptr(). Internally, all bpfptr_t operations are backed by the corresponding sockptr_t operations, which performs direct memcpy() on kernel pointers for copy_from/strncpy_from operations. Therefore, the code is always happy to dereference the bad pointer to trigger a un-handle-able page fault and in turn an oops. However, this is not supposed to happen because at that point the eBPF program is already verified and should not cause a memory error.
Sample KASAN trace:

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\nBPF: Fix potential bad pointer dereference in bpf_sys_bpf()\n\nThe bpf_sys_bpf() helper function allows an eBPF program to load another\neBPF program from within the kernel. In this case the argument union\nbpf_attr pointer (as well as the insns and license pointers inside) is a\nkernel address instead of a userspace address (which is the case of a\nusual bpf() syscall). To make the memory copying process in the syscall\nwork in both cases, bpfptr_t was introduced to wrap around the pointer\nand distinguish its origin. Specifically, when copying memory contents\nfrom a bpfptr_t, a copy_from_user() is performed in case of a userspace\naddress and a memcpy() is performed for a kernel address.\n\nThis can lead to problems because the in-kernel pointer is never checked\nfor validity. The problem happens when an eBPF syscall program tries to\ncall bpf_sys_bpf() to load a program but provides a bad insns pointer --\nsay 0xdeadbeef -- in the bpf_attr union. The helper calls __sys_bpf()\nwhich would then call bpf_prog_load() to load the program.\nbpf_prog_load() is responsible for copying the eBPF instructions to the\nnewly allocated memory for the program; it creates a kernel bpfptr_t for\ninsns and invokes copy_from_bpfptr(). Internally, all bpfptr_t\noperations are backed by the corresponding sockptr_t operations, which\nperforms direct memcpy() on kernel pointers for copy_from/strncpy_from\noperations. Therefore, the code is always happy to dereference the bad\npointer to trigger a un-handle-able page fault and in turn an oops.\nHowever, this is not supposed to happen because at that point the eBPF\nprogram is already verified and should not cause a memory error.\n\nSample KASAN trace:\n\n[ 25.685056][ T228] ==================================================================\n[ 25.685680][ T228] BUG: KASAN: user-memory-access in copy_from_bpfptr+0x21/0x30\n[ 25.686210][ T228] Read of size 80 at addr 00000000deadbeef by task poc/228\n[ 25.686732][ T228]\n[ 25.686893][ T228] CPU: 3 PID: 228 Comm: poc Not tainted 5.19.0-rc7 #7\n[ 25.687375][ T228] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS d55cb5a 04/01/2014\n[ 25.687991][ T228] Call Trace:\n[ 25.688223][ T228] \u003cTASK\u003e\n[ 25.688429][ T228] dump_stack_lvl+0x73/0x9e\n[ 25.688747][ T228] print_report+0xea/0x200\n[ 25.689061][ T228] ? copy_from_bpfptr+0x21/0x30\n[ 25.689401][ T228] ? _printk+0x54/0x6e\n[ 25.689693][ T228] ? _raw_spin_lock_irqsave+0x70/0xd0\n[ 25.690071][ T228] ? copy_from_bpfptr+0x21/0x30\n[ 25.690412][ T228] kasan_report+0xb5/0xe0\n[ 25.690716][ T228] ? copy_from_bpfptr+0x21/0x30\n[ 25.691059][ T228] kasan_check_range+0x2bd/0x2e0\n[ 25.691405][ T228] ? copy_from_bpfptr+0x21/0x30\n[ 25.691734][ T228] memcpy+0x25/0x60\n[ 25.692000][ T228] copy_from_bpfptr+0x21/0x30\n[ 25.692328][ T228] bpf_prog_load+0x604/0x9e0\n[ 25.692653][ T228] ? cap_capable+0xb4/0xe0\n[ 25.692956][ T228] ? security_capable+0x4f/0x70\n[ 25.693324][ T228] __sys_bpf+0x3af/0x580\n[ 25.693635][ T228] bpf_sys_bpf+0x45/0x240\n[ 25.693937][ T228] bpf_prog_f0ec79a5a3caca46_bpf_func1+0xa2/0xbd\n[ 25.694394][ T228] bpf_prog_run_pin_on_cpu+0x2f/0xb0\n[ 25.694756][ T228] bpf_prog_test_run_syscall+0x146/0x1c0\n[ 25.695144][ T228] bpf_prog_test_run+0x172/0x190\n[ 25.695487][ T228] __sys_bpf+0x2c5/0x580\n[ 25.695776][ T228] __x64_sys_bpf+0x3a/0x50\n[ 25.696084][ T228] do_syscall_64+0x60/0x90\n[ 25.696393][ T228] ? fpregs_assert_state_consistent+0x50/0x60\n[ 25.696815][ T228] ? exit_to_user_mode_prepare+0x36/0xa0\n[ 25.697202][ T228] ? syscall_exit_to_user_mode+0x20/0x40\n[ 25.697586][ T228] ? do_syscall_64+0x6e/0x90\n[ 25.697899][ T228] entry_SYSCALL_64_after_hwframe+0x63/0xcd\n[ 25.698312][ T228] RIP: 0033:0x7f6d543fb759\n[ 25.698624][ T228] Code: 08 5b 89 e8 5d c3 66 2e 0f 1f 84 00 00 00 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d \n---truncated---",

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
No CAPEC attack patterns related to this CWE.
