While we could "fix" with a more complex approach there could be consequences to expectations so the patch takes the preventive approach of "disallow such config".

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

ARM: davinci: da850-evm: Avoid NULL pointer dereference

With newer versions of GCC, there is a panic in da850_evm_config_emac() when booting multi_v5_defconfig in QEMU under the palmetto-bmc machine:

Unable to handle kernel NULL pointer dereference at virtual address 00000020 pgd = (ptrval) [00000020] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 5.15.0 #1 Hardware name: Generic DT based system PC is at da850_evm_config_emac+0x1c/0x120 LR is at do_one_initcall+0x50/0x1e0

The emac_pdata pointer in soc_info is NULL because davinci_soc_info only gets populated on davinci machines but da850_evm_config_emac() is called on all machines via device_initcall().

Move the rmii_en assignment below the machine check so that it is only dereferenced when running on a supported SoC.(CVE-2021-47631)

In the Linux kernel, the following vulnerability has been resolved:

video: fbdev: nvidiafb: Use strscpy() to prevent buffer overflow

Coverity complains of a possible buffer overflow. However, given the 'static' scope of nvidia_setup_i2c_bus() it looks like that can't happen after examiniing the call sites.

CID 19036 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)

1. fixed_size_dest: You might overrun the 48-character fixed-size string chan->adapter.name by copying name without checking the length.
2. parameter_as_source: Note: This defect has an elevated risk because the source argument is a parameter of the current function. 89 strcpy(chan->adapter.name, name);

Fix this warning by using strscpy() which will silence the warning and prevent any future buffer overflows should the names used to identify the channel become much longer.(CVE-2021-47642)

In the Linux kernel, the following vulnerability has been resolved:

dm integrity: fix memory corruption when tag_size is less than digest size

It is possible to set up dm-integrity in such a way that the "tag_size" parameter is less than the actual digest size. In this situation, a part of the digest beyond tag_size is ignored.

In this case, dm-integrity would write beyond the end of the ic->recalc_tags array and corrupt memory. The corruption happened in integrity_recalc->integrity_sector_checksum->crypto_shash_final.

Fix this corruption by increasing the tags array so that it has enough padding at the end to accomodate the loop in integrity_recalc() being able to write a full digest size for the last member of the tags array.(CVE-2022-49044)

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: Check for potential null return of kmalloc_array()

As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference. Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.(CVE-2022-49055)

In the Linux kernel, the following vulnerability has been resolved:

scsi: libfc: Fix use after free in fc_exch_abts_resp()

fc_exch_release(ep) will decrease the ep's reference count. When the reference count reaches zero, it is freed. But ep is still used in the following code, which will lead to a use after free.

Return after the fc_exch_release() call to avoid use after free.(CVE-2022-49114)

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj

This issue takes place in an error path in amdgpu_cs_fence_to_handle_ioctl(). When info->in.what falls into default case, the function simply returns -EINVAL, forgetting to decrement the reference count of a dma_fence obj, which is bumped earlier by amdgpu_cs_get_fence(). This may result in reference count leaks.

Fix it by decreasing the refcount of specific object before returning the error…

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit()

The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32 values that come from the user via the submit_lookup_cmds() function. This addition could lead to an integer wrapping bug so use size_add() to prevent that.

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr()

Extended the mi_enum_attr() function interface with an additional parameter, struct ntfs_inode *ni, to allow marking the inode as bad as soon as an error is detected.(CVE-2024-52560)

In the Linux kernel, the following vulnerability has been resolved:

crypto: qat/qat_4xxx - fix off by one in uof_get_name()

The fw_objs[] array has "num_objs" elements so the > needs to be >= to prevent an out of bounds read.(CVE-2024-53162)

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix use-after-free of signing key

Customers have reported use-after-free in @ses->auth_key.response with SMB2.1 + sign mounts which occurs due to following race:

task A task B cifs_mount() dfs_mount_share() get_session() cifs_mount_get_session() cifs_send_recv() cifs_get_smb_ses() compound_send_recv() cifs_setup_session() smb2_setup_request() kfree_sensitive() smb2_calc_signature() crypto_shash_setkey() UAF

Fix this by ensuring that we have a valid @ses->auth_key.response by checking whether @ses->ses_status is SES_GOOD or SES_EXITING with @ses->ses_lock held. After commit 24a9799aa8ef ("smb: client: fix UAF in smb2_reconnect_server()"), we made sure to call ->logoff() only when @ses was known to be good (e.g. valid ->auth_key.response), so it's safe to access signing key when @ses->ses_status == SES_EXITING.(CVE-2024-53179)

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: bsg: Set bsg_queue to NULL after removal

Currently, this does not cause any issues, but I believe it is necessary to set bsg_queue to NULL after removing it to prevent potential use-after-free (UAF) access.(CVE-2024-54458)

In the Linux kernel, the following vulnerability has been resolved:

KVM: x86: Play nice with protected guests in complete_hypercall_exit()

Use is_64_bit_hypercall() instead of is_64_bit_mode() to detect a 64-bit hypercall when completing said hypercall. For guests with protected state, e.g. SEV-ES and SEV-SNP, KVM must assume the hypercall was made in 64-bit mode as the vCPU state needed to detect 64-bit mode is unavailable.

f2fs: fix to shrink read extent node in batches

We use rwlock to protect core structure data of extent tree during its shrink, however, if there is a huge number of extent nodes in extent tree, during shrink of extent tree, it may hold rwlock for a very long time, which may trigger kernel hang issue.

This patch fixes to shrink read extent node in batches, so that, critical region of the rwlock can be shrunk to avoid its extreme long time hold.(CVE-2024-41935)

In the Linux kernel, the following vulnerability has been resolved:

vrf: revert "vrf: Remove unnecessary RCU-bh critical section"

This reverts commit 504fc6f4f7f681d2a03aa5f68aad549d90eab853.

dev_queue_xmit_nit is expected to be called with BH disabled. __dev_queue_xmit has the following:

    /* Disable soft irqs for various locks below. Also
     * stops preemption for RCU.

Joint work with Lion Ackermann [email protected]

In the Linux kernel, the following vulnerability has been resolved:

net: sched: Disallow replacing of child qdisc from one parent to another

Lion Ackermann was able to create a UAF which can be abused for privilege escalation with the following script

Step 1. create root qdisc tc qdisc add dev lo root handle 1:0 drr

step2. a class for packet aggregation do demonstrate uaf tc class add dev lo classid 1:1 drr

step3. a class for nesting tc class add dev lo classid 1:2 drr

step4. a class to graft qdisc to tc class add dev lo classid 1:3 drr

step5. tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024

step6. tc qdisc add dev lo parent 1:2 handle 3:0 drr

step7. tc class add dev lo classid 3:1 drr

step 8. tc qdisc add dev lo parent 3:1 handle 4:0 pfifo

step 9. Display the class/qdisc layout

tc class ls dev lo class drr 1:1 root leaf 2: quantum 64Kb class drr 1:2 root leaf 3: quantum 64Kb class drr 3:1 root leaf 4: quantum 64Kb

tc qdisc ls qdisc drr 1: dev lo root refcnt 2 qdisc plug 2: dev lo parent 1:1 qdisc pfifo 4: dev lo parent 3:1 limit 1000p qdisc drr 3: dev lo parent 1:2

step10. trigger the bug <=== prevented by this patch tc qdisc replace dev lo parent 1:3 handle 4:0

step 11. Redisplay again the qdiscs/classes

tc class ls dev lo class drr 1:1 root leaf 2: quantum 64Kb class drr 1:2 root leaf 3: quantum 64Kb class drr 1:3 root leaf 4: quantum 64Kb class drr 3:1 root leaf 4: quantum 64Kb

tc qdisc ls qdisc drr 1: dev lo root refcnt 2 qdisc plug 2: dev lo parent 1:1 qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p qdisc drr 3: dev lo parent 1:2

Observe that a) parent for 4:0 does not change despite the replace request. There can only be one parent. b) refcount has gone up by two for 4:0 and c) both class 1:3 and 3:1 are pointing to it.

Step 12. send one packet to plug echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001)) step13. send one packet to the grafted fifo echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))

step14. lets trigger the uaf tc class delete dev lo classid 1:3 tc class delete dev lo classid 1:1

The semantics of "replace" is for a del/add on the same node and not a delete from one node(3:1) and add to another node (1:3) as in step10. While we could "fix" with a more complex approach there could be consequences to expectations so the patch takes the preventive approach of "disallow such config".
